+        <p>
+          Microstate accounting can be used to measure how much time the Erlang
+          runtime system spends doing various tasks. It is designed to be as
+          lightweight as possible, but there will be some overhead when this
+          is enabled. Microstate accounting is meant to be a profiling tool
+          to help figure out performance bottlenecks.
+          To <c>start</c>/<c>stop</c>/<c>reset</c> microstate_accounting you use
+          the system_flag

+          <c>erlang:statistics(microstate_accounting)</c> returns a list of maps

+          <c>type</c> and <c>id</c> fields that can be used to identify what
+          thread it is, and also a counters field that contains data about how

+  end, erlang:statistics(microstate_accounting)).
+        </pre>
+        <p>
+          It is important to note that these values are not guaranteed to be
+          the exact time spent in each state. This is because of various

+/* The defines below are used to instrument the vm code

+ * of each define. One that has a cached ErtsMsAcc *
+ * that it can use, and one that does not.
+ * The cached values are necessary to have in order to get
+ * low enough overhead when running without msacc enabled.
+ *
+ * The two most common patterns to use the function with are:
+ *
+ *   ERTS_MSACC_PUSH_AND_SET_STATE(ERTS_MSACC_STATE_NEWSTATE);
+ *     ... call other function in new state ...
+ *   ERTS_MSACC_POP_STATE();
+ *
+ * Note that the erts_msacc_push* function declare new variables, so
+ * to conform with C89 we have to call it in the beginning of a function.
+ * We might not want to change state it the beginning though, so we use this:
+ *
+ *   ERTS_MSACC_PUSH_STATE();
+ *     ... some other code ...
+ *   ERTS_MSACC_SET_STATE_CACHED(ERTS_MSACC_STATE_NEWSTATE);
+ *     ... call other function in new state ...
+ *   ERTS_MSACC_POP_STATE();
+ *
+ * Notice that we used the cached version of set_state as push_state already
+ * read the erts_msacc_enabled to the cache.
+ *
+ * Most macros also have other variants with the suffix _m which means that
+ * they are known to only be called in managed threads, or with the _x suffix
+ * which means that it should only be used in an emulator compiled with
+ * extended states.
+ *
+ * Here is a listing of the entire api:
+ *
+ *  void ERTS_MSACC_DECLARE_CACHE()
+ *  void ERTS_MSACC_UPDATE_CACHE()
+ *  void ERTS_MSACC_IS_ENABLED()

- * Some notes about how inet (currently only tcp) works on OSE.
- * The driver uses OSE signals to communicate with the one_inet
- * process. Because of the difference in how signals and file descriptors
- * work the whole select/deselect mechanic is very different.
- * In ose when a sock_select is done a function is called. That function
- * notes the changes that the driver want to do, but does not act on it.
- * later when the function returns the new desired state is compared
- * to the previous state and the apprioriate actions are taken. The action
- * is usually to either request more data from the stack or stop requesting
- * data.
- *
- * One thing to note is that the driver never does select/deselect. It always
- * listens for the signals. Flow of data is regulated by sending or not sending
- * signals to the ose inet process.
- *
- * The interesting functions to look at are:
- *  * inet_driver_select : called when sock_select is called
- *  * tcp_inet_ose_dispatch_signal : checks state changes and sends new signals
- *  * tcp_inet_drv_output_ose : ready output callback, reads signals and calls
- *                              dispatch_signal
- *  * tcp_inet_drv_input_ose : ready input callback.

 /*
- * After a vfork() (or fork()) the child exec()s to this program which
- * sets up the child and exec()s to the user program (see spawn_start()
- * in sys.c and ticket OTP-4389).
+ * This program is started at erts startup and all fork's that
+ * have to be done are done in here. This is done for a couple
+ * of reasons:
+ *  - Allow usage of fork without a memory explosion.
+ *  -- we do not want to use vfork, as it blocks the VM
+ *     until the execv is done, and if the program that
+ *     is to be executed is on an NFS that is unavailable,
+ *     the execv can block for a very long time.
+ *  -- we cannot do fork inside the VM as that would temporarily
+ *     duplicate the memory usage of the VM per parallel exec.
+ *
+ * Some implementation notes:
+ *  - A single Unix Domain Socket is setup in between the VM and
+ *    this program. Over that UDS the file descriptors that should
+ *    be used to talk to the child program are sent.
+ *    The actual command to execute, together with options and the
+ *    environment, is sent over the pipe represented by the
+ *    file descriptors mentioned above. We don't send the
+ *    command over the UDS as that would increase the likely hood
+ *    that it's buffer would be full.
+ *
+ *  - Since it is this program that execv's, it has to take care of
+ *    all the SIGCHLD signals that the child programs generate. The
+ *    signals are received and the pid+exit reason is sent as data
+ *    on the UDS to the VM. The VM is then able to map the pid to the
+ *    port of the child program that just exited and deliver the status
+ *    code if requested.

-  [arndt] In most Unix systems, including Solaris 2.5, 'fork' allocates memory
-  in swap space for the child of a 'fork', whereas 'vfork' does not do this.
-  The natural call to use here is therefore 'vfork'. Due to a bug in
-  'vfork' in Solaris 2.5 (apparently fixed in 2.6), using 'vfork'
-  can be dangerous in what seems to be these circumstances:
-      If the child code under a vfork sets the signal action to SIG_DFL
-      (or SIG_IGN)
-      for any signal which was previously set to a signal handler, the
-      state of the parent is clobbered, so that the later arrival of
-      such a signal yields a sigsegv in the parent. If the signal was
-      not set to a signal handler, but ignored, all seems to work.
-  If you change the forking code below, beware of this.

-     * Historical:
-     *
-     * "Note about nonblocking I/O.
-     *
-     * At least on Solaris, setting the write end of a TTY to nonblocking,
-     * will set the input end to nonblocking as well (and vice-versa).
-     * If erl is run in a pipeline like this:  cat | erl
-     * the input end of the TTY will be the standard input of cat.
-     * And cat is not prepared to handle nonblocking I/O."
-     *
-     * Actually, the reason for this is not that the tty itself gets set
-     * in non-blocking mode, but that the "input end" (cat's stdin) and
-     * the "output end" (erlang's stdout) are typically the "same" file
-     * descriptor, dup()'ed from a single fd by one of this process'
-     * ancestors.
-     *
-     * The workaround for this problem used to be a rather bad kludge,
-     * interposing an extra process ("internal cat") between erlang's
-     * stdout and the original stdout, allowing erlang to set its stdout
-     * in non-blocking mode without affecting the stdin of the preceding
-     * process in the pipeline - and being a kludge, it caused all kinds
-     * of weird problems.
-     *
-     * So, this is the current logic:
-     *
-     * The only reason to set non-blocking mode on the output fd at all is
-     * if it's something that can cause a write() to block, of course,
-     * i.e. primarily if it points to a tty, socket, pipe, or fifo. 
-     *
-     * If we don't set non-blocking mode when we "should" have, and output
-     * becomes blocked, the entire runtime system will be suspended - this
-     * is normally bad of course, and can happen fairly "easily" - e.g. user
-     * hits ^S on tty - but doesn't necessarily happen.
-     * 
-     * If we do set non-blocking mode when we "shouldn't" have, the runtime
-     * system will end up seeing EOF on the input fd (due to the preceding
-     * process dying), which typically will cause the entire runtime system
-     * to terminate immediately (due to whatever erlang process is seeing
-     * the EOF taking it as a signal to halt the system). This is *very* bad.
-     * 
-     * I.e. we should take a conservative approach, and only set non-
-     * blocking mode when we a) need to, and b) are reasonably certain
-     * that it won't be a problem. And as in the example above, the problem
-     * occurs when input fd and output fd point to different "things".
-     *
-     * However, determining that they are not just the same "type" of
-     * "thing", but actually the same instance of that type of thing, is
-     * unreasonably complex in many/most cases.
-     *
-     * Also, with pipes, sockets, and fifos it's far from obvious that the
-     * user *wants* non-blocking output: If you're running erlang inside
-     * some complex pipeline, you're probably not running a real-time system
-     * that must never stop, but rather *want* it to suspend if the output
-     * channel is "full".
-     *
-     * So, the bottom line: We will only set the output fd non-blocking if
-     * it points to a tty, and either a) the input fd also points to a tty,
-     * or b) we can make sure that setting the output fd non-blocking
-     * doesn't interfere with someone else's input, via a somewhat milder
-     * kludge than the above.
-     *
-     * Also keep in mind that while this code is almost exclusively run as
-     * a result of an erlang open_port({fd,0,1}, ...), that isn't the only
-     * case - it can be called with any old pre-existing file descriptors,
-     * the relations between which (if they're even two) we can only guess
-     * at - still, we try our best...
-     *
-     * Added note OTP 18: Some systems seem to use stdout/stderr to log data
-     * using unix pipes, so we cannot allow the system to block on a write.
-     * Therefore we use an async thread to write the data to fd's that could
-     * not be set to non-blocking. When no async threads are available we
-     * fall back on the old behaviour.
-     *
-     * Also the guarantee about what is delivered to the OS has changed.
-     * Pre 18 the fd driver did no flushing of data before terminating.
-     * Now it does. This is because we want to be able to guarantee that things
-     * such as escripts and friends really have outputted all data before
-     * terminating. This could potentially block the termination of the system
-     * for a very long time, but if the user wants to terminate fast she should
-     * use erlang:halt with flush=false.

-		       obtained this way, and set *that* one in non-blocking
-		       mode. (Yes, this is a kludge.)
-
-		       However, re-opening the tty may fail in a couple of
-		       (unusual) cases:
-
-		       1) The name of the tty (or an equivalent one, i.e.

-			  wherever ttyname() looks for it), and isn't
-			  equivalent to any of those that do live in the
-			  "standard" place - this should be *very* unusual.
-
-		       2) Permissions on the tty don't allow us to open it -
-			  it's perfectly possible to have an fd open to an
-			  object whose permissions wouldn't allow us to open
-			  it. This is not as unusual as it sounds, one case
-			  is if the user has su'ed to someone else (not
-			  root) - we have a read/write fd open to the tty
-			  (because it has been inherited all the way down
-			  here), but we have neither read nor write
-			  permission for the tty.
-
-		       In these cases, we finally give up, and don't set the

+     * Historical:
+     *
+     * "Note about nonblocking I/O.
+     *
+     * At least on Solaris, setting the write end of a TTY to nonblocking,
+     * will set the input end to nonblocking as well (and vice-versa).
+     * If erl is run in a pipeline like this:  cat | erl
+     * the input end of the TTY will be the standard input of cat.
+     * And cat is not prepared to handle nonblocking I/O."
+     *
+     * Actually, the reason for this is not that the tty itself gets set
+     * in non-blocking mode, but that the "input end" (cat's stdin) and
+     * the "output end" (erlang's stdout) are typically the "same" file
+     * descriptor, dup()'ed from a single fd by one of this process'
+     * ancestors.
+     *
+     * The workaround for this problem used to be a rather bad kludge,
+     * interposing an extra process ("internal cat") between erlang's
+     * stdout and the original stdout, allowing erlang to set its stdout
+     * in non-blocking mode without affecting the stdin of the preceding
+     * process in the pipeline - and being a kludge, it caused all kinds
+     * of weird problems.
+     *
+     * So, this is the current logic:
+     *
+     * The only reason to set non-blocking mode on the output fd at all is
+     * if it's something that can cause a write() to block, of course,
+     * i.e. primarily if it points to a tty, socket, pipe, or fifo. 
+     *
+     * If we don't set non-blocking mode when we "should" have, and output
+     * becomes blocked, the entire runtime system will be suspended - this
+     * is normally bad of course, and can happen fairly "easily" - e.g. user
+     * hits ^S on tty - but doesn't necessarily happen.
+     * 
+     * If we do set non-blocking mode when we "shouldn't" have, the runtime
+     * system will end up seeing EOF on the input fd (due to the preceding
+     * process dying), which typically will cause the entire runtime system
+     * to terminate immediately (due to whatever erlang process is seeing
+     * the EOF taking it as a signal to halt the system). This is *very* bad.
+     * 
+     * I.e. we should take a conservative approach, and only set non-
+     * blocking mode when we a) need to, and b) are reasonably certain
+     * that it won't be a problem. And as in the example above, the problem
+     * occurs when input fd and output fd point to different "things".
+     *
+     * However, determining that they are not just the same "type" of
+     * "thing", but actually the same instance of that type of thing, is
+     * unreasonably complex in many/most cases.
+     *
+     * Also, with pipes, sockets, and fifos it's far from obvious that the
+     * user *wants* non-blocking output: If you're running erlang inside
+     * some complex pipeline, you're probably not running a real-time system
+     * that must never stop, but rather *want* it to suspend if the output
+     * channel is "full".
+     *
+     * So, the bottom line: We will only set the output fd non-blocking if
+     * it points to a tty, and either a) the input fd also points to a tty,
+     * or b) we can make sure that setting the output fd non-blocking
+     * doesn't interfere with someone else's input, via a somewhat milder
+     * kludge than the above.
+     *
+     * Also keep in mind that while this code is almost exclusively run as
+     * a result of an erlang open_port({fd,0,1}, ...), that isn't the only
+     * case - it can be called with any old pre-existing file descriptors,
+     * the relations between which (if they're even two) we can only guess
+     * at - still, we try our best...
+     *
+     * Added note OTP 18: Some systems seem to use stdout/stderr to log data
+     * using unix pipes, so we cannot allow the system to block on a write.
+     * Therefore we use an async thread to write the data to fd's that could
+     * not be set to non-blocking. When no async threads are available we
+     * fall back on the old behaviour.
+     *
+     * Also the guarantee about what is delivered to the OS has changed.
+     * Pre 18 the fd driver did no flushing of data before terminating.
+     * Now it does. This is because we want to be able to guarantee that things
+     * such as escripts and friends really have outputted all data before
+     * terminating. This could potentially block the termination of the system
+     * for a very long time, but if the user wants to terminate fast she should
+     * use erlang:halt with flush=false.

+		       1) The name of the tty (or an equivalent one, i.e.
+			  same major/minor number) can't be found, because
+			  it actually lives somewhere other than /dev (or
+			  wherever ttyname() looks for it), and isn't
+			  equivalent to any of those that do live in the
+			  "standard" place - this should be *very* unusual.
+
+		       2) Permissions on the tty don't allow us to open it -
+			  it's perfectly possible to have an fd open to an
+			  object whose permissions wouldn't allow us to open
+			  it. This is not as unusual as it sounds, one case
+			  is if the user has su'ed to someone else (not
+			  root) - we have a read/write fd open to the tty
+			  (because it has been inherited all the way down
+			  here), but we have neither read nor write
+			  permission for the tty.
+
+		       In these cases, we finally give up, and don't set the
+		       output fd in non-blocking mode. */

-%%% An optimization: erl_prim_loader gets the chance of loading many

-%%% for the disk. The optimization is not tried unless the loader is
-%%% "efile" and there is a non-empty pool of threads.
-%%%
-%%% Many threads are needed to get a good result, so it would be
-%%% beneficial to load several applications in parallel. However,
-%%% measurements show that the file system handles one directory at a
-%%% time, regardless if parallel threads are created for files on
-%%% several directories (a guess: writing the meta information when

-BONK! In Erlang for You
-by
-LENNART OHMAN & MARCUS ARENDT
-
-After an idea of Mike Darweesh.
-Special thanks to Peter Jansson for creating the bitmaps.
-Ported to GS 1.1 by Markus Torpvret and Anders Dahlin.

-
-INSTRUCTIONS
-- Hit as many creatures as possible using the left mouse-button.                                
-- After every 25 hits You will advance one level. For each level You get one bomb. 
-- Pushing the middle or right mouse-button, in any square, drops a bomb which     
-wipes out everything.                                                                                                            
-- The game ends when 10 creatures has escaped from beeing bonked.

-ABOUT ERLANG
-Erlang is a programming language for building robust concurrent systems. It is a single assignment, symbolic language with built in concurrency. It provides unique facilities for error handling and for reloading updated modules in running systems. Erlang was designed and implemented by Joe Armstrong, Robert Virding, and Mike Williams at Ellemtel (now Ericsson Utvecklings AB).

-%% Differences are, explanation why and source of change in parenthesis:
-%%
-%%	-  Buttons looks different (gs feature)
-%%	-  The black box around "Black to draw" have been removed. (me)
-%%	-  The Colour and Level menues have been moved directly down to the 
-%%	     'Status' box. (usability update, my addition)
-%%	-  The mouse pointer does not change into a watch when the computer

-%%	-  Buttons does not flash when being beeped. (not supported in gs)

-    <title>Code Path Cache</title>
-    <p>The code server incorporates a code path cache. The cache
-      functionality is disabled by default. To activate it, start
-      the emulator with the command line flag <c>-code_path_cache</c>
-      or call <c>code:rehash()</c>. When the cache is created (or
-      updated), the code server searches for modules in the code path
-      directories. This may take some time if the the code path is long.
-      After the cache creation, the time for loading modules in a large
-      system (one with a large directory structure) is significantly
-      reduced compared to having the cache disabled. The code server
-      is able to look up the location of a module from the cache in
-      constant time instead of having to search through the code path
-      directories.</p>
-    <p>Application resource files (<c>.app</c> files) are also stored
-      in the code path cache. This feature is used by the application
-      controller (see
-      <seealso marker="application">application(3)</seealso>) to load
-      applications efficiently in large systems.</p>
-    <p>Note that when the code path cache is created (or updated), any
-      relative directory names in the code path are converted to
-      absolute.</p>

-	    Erlang/OTP has been ported to the realtime operating
-	    system OSE. The port supports both smp and non-smp
-	    emulator. For details around the port and how to started
-	    see the User's Guide in the <seealso
-	    marker="ose:ose_intro">ose</seealso> application. </p>
-          <p>
-	    Note that not all parts of Erlang/OTP has been ported. </p>
-          <p>
-	    Notable things that work are: non-smp and smp emulators,
-	    OSE signal interaction, crypto, asn1, run_erl/to_erl,
-	    tcp, epmd, distribution and most if not all non-os
-	    specific functionality of Erlang.</p>
-          <p>
-	    Notable things that does not work are: udp/sctp, os_mon,
-	    erl_interface, binding of schedulers.</p>

-  <description>
-    <p>Writing Linked-in drivers that also work on Enea OSE is very similar for
-    how you would do it for Unix. The difference from Unix is that
-    driver_select, ready_input and ready_output all work with signals
-    instead of file descriptors. This means that the driver_select is
-    used to specify which type of signal should trigger calls to
-    ready_input/ready_output. The functions described below are available
-    to driver programmers on Enea OSE to facilitate this.

-    <title>Starting Erlang/OTP</title>
-    <p>
-      Starting Erlang/OTP on OSE is not as simple as on Unix/Windows (yet).
-      First of all you have to explicitly use the beam (or beam.smp) executables
-      found in erts-X.Y.Z/bin as the load module that you run. This in turn
-      means that you have to supply the raw beam arguments to the emulator
-      when starting. Fortunately <c>erl</c> on Unix/Windows has a
-      undocumented flag called <c>-emu_args_exit</c> that can be used to
-      figure out what the arguments to beam look like. For example:</p>
-      <code># erl +Mut false +A 10 +S 4:4 +Muycs256 +P 2096 +Q 2096 -emu_args_exit
--Mut
-false
--A
-10
--S
-4:4
--Muycs256
--P
-2096
--Q
-2096
---
--root
-/usr/local/lib/erlang
--progname
-erl
---
--home
-/home/erlang
---</code>
-    <p>
-      The arguments are printed on separate lines to make it possible to know
-      what has to be quoted with &quot;. Each line is one quotable unit.
-      So taking the arguments above you can supply them to pm_create or
-      just execute directly on the command line. For example:</p>
-      <code>rtose@acp3400> pm_install erlang /mst/erlang/erts-6.0/bin/beam.smp
-rtose@acp3400> pm_create -c ARGV="-Mut false -A 10 -S 4:4 -Muycs256 -P 2096 -Q 2099 -- -root /mst/erlang -progname erl -- -home /mst/erlang --" erlang
-pid: 0x110059
-rtose@acp3400> pm_start 0x110059</code>
-    <p>
-      Also note that since we are running erl to figure out the arguments on a
-      separate machine the paths have to be updated. In the example above
-      <c>/usr/local/lib/erlang</c> was replaced by <c>/mst/erlang/</c>. The
-      goal is to in future releases not have to do the special argument handling
-      but for now (OTP 17.0) you have to do it.
-    </p>
-    <note>
-      Because of a limitation in the way the OSE handles stdio when starting
-      load modules using pm_install/create the Erlang shell only reads every
-      other command from stdin. However if you start Erlang using run_erl
-      you do not have this problem. So it is highly recommended that you
-      start Erlang using run_erl.
-    </note>
-  </section>
-
-  <section>
-    <title>run_erl and to_erl</title>
-    <p>
-      In OSE run_erl and to_erl are combined into a single load module called
-      run_erl_lm. Installing and starting the load module will add two new
-      shell commands called run_erl and to_erl. They work in exactly the same
-      way as the unix variants of run_erl and to_erl, except that the read
-      and write pipes have to be placed under the /pipe vm. One additional
-      option also exists to run_erl on ose:
-      <taglist>
-	<tag><c>-block Name</c></tag>
-	<item>The name of the install handle and block that will be created/used by
-	installing and exectuting the first part of the command. If nothing
-	if given the basename of the load module will be used for this value.
-	Example:
-	<code>pm_install erlang /path/to/erlang/vm/beam.smp
-run_erl -daemon -block erlang /pipe/ /mst/erlang_logs/ "beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"</code>
-	</item>
-      </taglist>
-      The same argument munching as when starting Erlang/OTP without run_erl
-      has to be done. If <c>-daemon</c> is given then all error printouts
-      are sent to the ramlog.
-      See also
-      <seealso marker="erts:run_erl">run_erl</seealso> for more details.
-    </p>
-    <p>
-      Below is an example of how to get started with <c>run_erl_lm</c>.
-      <code>rtose@acp3400> pm_install run_erl_lm /mst/erlang/erts-6.0/bin/run_erl_lm
-rtose@acp3400> pm_create run_erl_lm
-pid: 0x1c005d
-rtose@acp3400> pm_start 0x1c005d
-rtose@acp3400> mkdir /mst/erlang_log
-rtose@acp3400> run_erl -daemon /pipe/ /mst/erlang_log/ "/mst/erlang/erts-6.0/bin/beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"
-rtose@acp3400> to_erl
-Attaching to /pipe/erlang.pipe.1 (^C to exit)
-os:type().
-{ose,release}
-2>
-'to_erl' terminated.</code>
-      Note that Ctrl-C is used instead of Ctrl-D to exit the to_erl shell.
-    </p>
-  </section>
-
-  <section>
-    <title>epmd</title>
-    <p>
-      In OSE epmd will not be started automatically so if you want to use
-      Erlang distribution you have to manually start epmd.
-    </p>
-  </section>
-
-  <section>
-    <title>VM Process Priorities</title>
-    <p>
-      It is possible to set the priorities you want for the OSE processes that
-      thr emulator creates in the lmconf. An example of how to do it can be
-      found in the default lmconf file in
-      $ERL_TOP/erts/emulator/sys/ose/beam.lmconf.

-    <title>Introduction</title>
-    <p>The main way which programs on Enea OSE interact is through the
-    usage of message passing, much the same way as Erlang processes
-    communicate. There are two ways in which an Erlang programmer can
-    interact with the signals sent from other Enea OSE processes; either
-    through the provided <c>ose</c> module, or by writing a custom linked-in
-    driver. This User's Guide describes and provides examples for both
-    approaches.

-    <title>Signals in Erlang</title>
-    <p>Erlang/OTP on OSE provides a erlang module called
-    <seealso marker="ose:ose">ose</seealso> that can be used to interact
-    with other OSE processes using message passing. The api in the module
-    is very similar to the native OSE api, so for details of how the
-    functions work please refer to the official OSE documenation. Below
-    is an example usage of the API.
-    </p>
-    <code>1> P1 = ose:open("p1").
-#Port&gt;0.344>
-2> ose:hunt(P1,"p2").
-{#Port&gt;0.344>,1}
-3> P2 = ose:open("p2").
-#Port&gt;0.355>
-4> flush().
-Shell got {mailbox_up,#Port&gt;0.344>,{#Port&gt;0.344>,1},852189}
-ok
-5> ose:listen(P1,[1234]).
-ok
-6> ose:send(P2,ose:get_id(P1),1234,&gt;&gt;"hello">>).
-ok
-7> flush().
-Shell got {message,#Port&gt;0.344>,{852189,1245316,1234,&gt;&gt;"hello">>}}

-    <title>Signals in a Linked-in driver</title>
-    <p>
-      Writing Linked-in drivers for OSE is very similar to how it is done
-      for Unix/Windows. It is only the way in which the driver subscribes
-      and consumed external events that is different. In Unix (and Windows)
-      file descriptiors (and Event Objects) are used to select on. On OSE
-      we use signals to deliver the same functionality. There are two large
-      differences between a signal and an fd.
-    </p>
-    <p>
-      In OSE it is not possible for a signal number to be a unique identifier
-      for a resource in the same way as an fd is. For example; let's say we
-      implement a driver that does an asynchronous hunt that uses signal
-      number 1234 as the hunt_sig. If we want to be able to have multiple
-      hunt ports running at the same time we have to have someway of routing
-      the signal to the correct port. This is achieved by supplying a secondary
-      id that can be retrieved through the meta-data or payload of the signal,
-      e.g:
-      <code>ErlDrvEvent event = erl_drv_ose_event_alloc(1234,port,resolver);</code>
-      The event you get back from
-      <seealso marker="ose_erl_driver#erl_drv_ose_event_alloc">
-      erl_drv_ose_event_alloc</seealso> can then be used by
-      <seealso marker="erts:erl_driver#driver_select">driver_select</seealso>
-      to subscribe to signals. The first argument is just the signal number
-      that we are interested in. The second is the id that we choose to use,
-      in this case the port id that we got in the
-      <seealso marker="erts:driver_entry#start">start</seealso> callback is
-      used. The third argument is a function pointer to a function that can
-      be used to figure out the id from a given signal. The fourth argument can
-      point to any additional data you might want to associate with the event.
-      There is a complete. You can examine the data contained in the event with
-      <seealso marker="ose_erl_driver#erl_drv_ose_event_fetch">erl_drv_ose_event_fetch</seealso>
-      , eg:
-      <code>erl_drv_ose_event_fetch(event, &amp;signal, &amp;port, (void **)&amp;extra);</code>
-      example of what this could look like in
-      <seealso marker="#example">the next section</seealso>.
-      <note>It is very important to issue the driver_select call before
-      any of the signals you are interested in are sent. If driver_select
-      is called after the signal is sent, there is a high probability that it
-      will be lost.</note>
-    </p>
-    <p>
-      The other difference from unix is that in OSE the payload of the event
-      (i.e. the signal data) is already received when the ready_output/input
-      callbacks are called. This means that you access the data of a signal
-      by calling <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
-      erl_drv_ose_get_signal</seealso>. Additionally multiple signals might be
-      associated with the event, so you should call
-      <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
-      erl_drv_ose_get_signal</seealso> until <c>NULL</c> is returned.

+    <p>This first command enables microstate accounting for 1000 milliseconds.

+    <seealso marker="#reset-0"><c>reset/0</c></seealso> and
+    <seealso marker="#start-1"><c>start/1</c></seealso> for more details.
+    The second command prints the statistics gathered during that time.
+    First three general statistics are printed.</p>
+    <taglist>
+      <tag>Average real-time</tag>
+      <item>The average time spent collecting data in the threads.
+      This should be close to the time which data was collected.
+      </item>
+      <tag>System run-time</tag>
+      <item>The total run-time of all threads in the system.
+      This is what you get if you call <c>msacc:stats(total_runtime,Stats).</c>
+      </item>
+      <tag>Average scheduler run-time</tag>
+      <item>The average run-time for the schedulers.
+      This is the average amount of time the schedulers did not sleep.</item>
+    </taglist>
+    <p>Then one column per state is printed with a the percentage of time this
+    thread spent in the state out of it's own real-time. After the thread
+    specific time, the accumulated time for each type of thread is printed in
+    a similar format.</p>
+    <p>Since we have the average real-time and the percentage spent in each
+    state we can easily calculate the time spent in each state by multiplying
+    <c>Average thread real-time</c> with <c>Thread state %</c>, i.e. to
+    get the time Scheduler 1 spent in the emulator state we do
+    <c>1000513us * 0.13% = 1300us</c>.</p>

-      <p>
-	All functions in this module are deprecated and will be
-	removed in a future release.
-      </p>
-    </warning>
-    <p><c>overload</c> is a process that indirectly regulates the CPU
-      usage in the system. The idea is that a main application calls
-      function 
-      <seealso marker="#request/0"><c>request/0</c></seealso> 
-      before starting a major job and
-      proceeds with the job if the return value is positive; otherwise
-      the job must not be started.</p>
-    <p><c>overload</c> is part of the <c>SASL</c> application and all
-      configuration parameters are defined there.</p>
-    <p>A set of two intensities are maintained, the <c>total intensity</c>
-      and the <c>accept intensity</c>. For that purpose,
-      there are two configuration parameters, <c>MaxIntensity</c>
-      and <c>Weight</c>; both are measured in 1/second.</p>
-    <p>Then total and accept intensities are calculated as
-      follows. Assume that the time of the current call to
-      <c>request/0</c> is <c>T(n)</c> and that the time of the
-      previous call was <c>T(n-1)</c>.</p>
-    <list type="bulleted">
-      <item>
-        <p>The current <c>total intensity</c>, denoted
-          <c>TI(n)</c>, is calculated according to the formula</p>
-        <p><c>TI(n) = exp(-Weight*(T(n) - T(n-1)) * TI(n-1) +  Weight</c>,</p>
-        <p>where <c>TI(n-1)</c> is the previous <c>total intensity</c>.</p>
-      </item>
-      <item>
-        <p>The current <c>accept intensity</c>, denoted
-          <c>AI(n)</c>, is determined by the formula</p>
-        <p><c>AI(n) = exp(-Weight*(T(n) - T(n-1)) * AI(n-1) + Weight</c>,</p>
-        <p>where <c>AI(n-1)</c> is the previous <c>accept intensity</c>,
-          if the value of <c>exp(-Weight*(T(n) - T(n-1)) * AI(n-1)</c>
-          is less than <c>MaxIntensity</c>. Otherwise the value is</p>
-        <p><c>AI(n) = exp(-Weight*(T(n) - T(n-1)) * AI(n-1)</c></p>
-      </item>
-    </list>
-    <p>The value of configuration parameter <c>Weight</c> controls the
-      speed with which the calculations of intensities react to
-      changes in the underlying input intensity. The inverted value of
-      <c>Weight</c>, <c>T = 1/Weight</c>, can be thought of as the
-      "time constant" of the intensity calculation formulas. For example,
-      if <c>Weight = 0.1</c>, a change in the underlying input intensity is
-      reflected in <c>total intensity</c> and <c>accept intensity</c> within
-      about 10 seconds.</p>
-    <p>The overload process defines one alarm, which it sets using
-      <c>alarm_handler:set_alarm(Alarm)</c>. <c>Alarm</c> is defined
-      as follows:</p>
-    <taglist>
-      <tag><c>{overload, []}</c></tag>
-      <item>
-        <p>This alarm is set when the current <c>accept intensity</c> exceeds
-          <c>MaxIntensity</c>.</p>
-      </item>
-    </taglist>
-    <p>A new request is not accepted until the current <c>accept
-      intensity</c> has fallen below <c>MaxIntensity</c>. To prevent the
-      overload process from generating many set/reset alarms, the
-      alarm is not reset until the current <c>accept intensity</c> has fallen
-      below 75% of <c>MaxIntensity</c>; it is not until then that
-      the alarm can be set again.</p>

-%%% This is a rewrite of overload from BS.3, by Peter Högfeldt.
-%%%
-%%% DESCRIPTION
-%%%
-%%% This module implements a server process that keeps record of the
-%%% intensity of calls of the request/0 function, and answers accept or
-%%% reject depending on if the current average intensity is not greater 
-%%% than a specified maximum intensity.
-%%%
-%%% The intensity i is calculated according to the formula:
-%%%    i(n) = exp(-K*(T(n) - T(n-1)))*i(n-1) + Kappa
-%%% where i(n) is the intensity at event n, Kappa is a constant, and
-%%% T(n) is the time at event n.
-%%%
-%%% The constant Kappa can be thought of as 1 / T, where T is the time 
-%%% constant. Kappa is externally referred to as Weight.
-%%%  
-%%% We keep track of two intensities: the total call intensity and the 
-%%% intensity of accepted calls.
-%%%-----------------------------------------------------------------
-%%% TODO
-%%%
-%%% 3. Hysteresis.

-===========================================================================
-                          OTP Test Server
-===========================================================================
-
-To compile the 'test_server' application you need to build and install
-a Erlang/OTP system from source. Get your open source Erlang/OTP from
-http://www.erlang.org/. The resulting "erlc" command must be in the
-search path for commands.
-
-The Erlang test_server application and the example tests are to be
-inserted into an existing source tree for Erlang/OTP.
-
-You don't run the Test Server or the tests from the source tree.
-Instead a test installation area $TESTROOT is used with the resulting
-directory structure
-
-  $TESTROOT/test_server
-  $TESTROOT/<app1>_test
-  $TESTROOT/<app2>_test
-  .
-  .
-
-For more details see the test_server documentation can be found in the
-"$ERL_TOP/lib/test_server/doc/html" directory.
-
-
-Unpacking the sources
----------------------
-
-Enter your Erlang/OTP source tree and unpack the OTP Test Server and
-optionally the test examples
-
-  % cd otp_src_RXX
-  % gunzip -c test_server-<VSN>.tar.gz | tar xf -
-  % gunzip -c emulator-YYYY-MM-DD.tar.gz | tar xf -
-  % gunzip -c stdlib-YYYY-MM-DD.tar.gz | tar xf -
-
-
-How to build and install the OTP Test Server
---------------------------------------------
-
-Set the ERL_TOP variable to the top directory of the source tree
-
-  % cd otp_src_RXX
-
-  % setenv ERL_TOP `pwd`
-  or
-  % export ERL_TOP=`pwd`
-
-If not done before you need to run the configure script
-
-  % ./configure
-
-Then build and install from the the base directory of the test_server
-application
-
-  % cd lib/test_server
-  % gmake release_tests TESTROOT=<some dir>
-
-
-How to build and install the example test suites
-------------------------------------------------
-
-If you want to build and install the example test suites
-you build and install from the the test directories
-
-  % cd $ERL_TOP/lib/stdlib/test
-  % gmake release_tests TESTROOT=<some dir>
-
-  % cd $ERL_TOP/erts/emulator/test
-  % gmake release_tests TESTROOT=<some dir>
-
-
-How to run OTP test suites
---------------------------
-
-First cd into $TESTROOT/test_server
-
-  % cd $TESTROOT/test_server
-
-Install the OTP Test Server framework
-
-  % erl
-  1> ts:install().
-
-Check which tests are available
-
-  2> ts:tests().
-  [...]
-
-Run the collections of test suites one at the time
-
-  3> ts:run(emulator).  (starts a xterm with an Erlang shell)
-  4> ts:run(stdlib).    (starts a xterm with an Erlang shell)
-
-or all at once
-
-  5> ts:run().          (the node running the tests will be in the background)
-
-Note that it is normal to see lots of error messages in the Erlang
-shell. The tests will stress the system with lots of invalid input to
-find problems in the error handling.
-
-Also note that a failing test case does not always indicate a bug in
-Erlang/OTP. Differences in the network setup, machine configuration
-etc may cause a test case to fail or time out.
-
-The result of the tests are recorded in the file named "index.html" in
-the "$TESTROOT/test_server" directory. You can follow the progress of
-tests suites not yet completed from "last_test.html".
-
-For more details see the test_server documentation can be found in the
-"$ERL_TOP/lib/test_server/doc/html" directory.

-    <title>Introduction</title>
-    <p><em>Test Server</em> is a portable test tool for automated
-    testing of Erlang programs and OTP applications. It provides an
-    interface for running test programs directly with Test Server 
-    as well as an interface for integrating Test Server
-    with a framework application. The latter makes it possible to use
-    Test Server as the engine of a higher level test tool
-    application.</p>
-
-    <p>It is strongly recommended that Test Server be used from inside
-    a framework application, rather than interfaced directly for
-    running test programs. Test Server can be pretty difficult to use
-    since it's a very general and quite extensive and complex
-    application. Furthermore, the <c>test_server_ctrl</c> functions
-    are not meant to be used from within the actual test programs. The
-    framework should handle communication with Test Server and deal
-    with the more complex aspects of this interaction automatically so
-    that a higher level interface may be provided for the tester. For
-    test tool usage to be productive, a simpler, more intuitive and 
-    (if required) more specific interface is required than what Test Server
-    can provide.</p>
-
-    <p>OTP delivers a general purpose framework for Test Server, called
-    <em>Common Test</em>. This application is a tool well suited for
-    automated black box testing of target systems of <em>any kind</em> 
-    (not necessarily implemented in Erlang). Common Test is also a very
-    useful tool for white box testing of Erlang programs and OTP
-    applications. Unless a more specific functionality and/or user 
-    interface is required (in which case you might need to implement 
-    your own framework), Common Test should do the job for 
-    you. Please read the Common Test User's Guide and reference manual 
-    for more information.</p>
-
-    <p>Under normal circumstances, knowledge about the Test Server
-    application is not required for using the Common Test framework.
-    However, if you want to use Test Server without a framework,
-    or learn how to integrate it with your own framework, please read on...
-    </p>
-    </section>
-    <section>
-    <title>Getting started</title>
-    <p>Testing when using Test Server is done by running test
-      suites. A test suite is a number of test cases, where each test
-      case tests one or more things. The test case is the smallest unit
-      that the test server deals with. One or more test cases are
-      grouped together into one ordinary Erlang module, which is called
-      a test suite. Several test suite modules can be grouped together
-      in special test specification files representing whole application
-      and/or system test "jobs".
-      </p>
-    <p>The test suite Erlang module must follow a certain interface,
-      which is specified by Test Server. See the section on writing
-      test suites for details about this.
-      </p>
-    <p>Each test case is considered a success if it returns to the
-      caller, no matter what the returned value is. An exception to this
-      is the return value <c>{skip, Reason}</c> which indicates that the
-      test case is skipped. A failure is specified as a crash, no matter
-      what the crash reason is.
-      </p>
-    <p>As a test suite runs, all information (including output to
-      stdout) is recorded in several different log files. A minimum of
-      information is displayed to the user console. This only include
-      start and stop information, plus a note for each failed test case.
-      </p>
-    <p>The result from each test case is recorded in an HTML log file
-      which is created for each test run. Every test case gets one row
-      in a table presenting total time, whether the case was successful
-      or not, if it was skipped, and possibly also a comment. The HTML
-      file has links to each test case's logfile, which may be viewed
-      from e.g. Netscape or any other HTML capable browser.
-      </p>
-    <p>The Test Server consists of three parts: 
-      </p>
-    <list type="bulleted">
-      <item>The part that executes the test suites and
-       provides support for the test suite author is called
-      <c>test_server</c>. This is described in the chapter about
-       writing test cases in this user's guide, and in the reference
-       manual for the <c>test_server</c> module.</item>
-      <item>The controlling part, which provides the low level
-       operator interface, starts and stops slave nodes and writes
-       log files, is called
-      <c>test_server_ctrl</c>. The Test Server Controller should not
-       be used directly when running tests. Instead a framework built
-       on top of it should be used. More information
-       about how to write your own framework can be found
-       in this user's guide and in the reference manual for the
-      <c>test_server_ctrl</c> module.</item>

-    <title>Definition of terms</title>
-    <taglist>
-      <tag><em>conf(iguration) case</em></tag>
-      <item>This is a group of test cases which need some specific
-       configuration. A conf case contains an initiation function which
-       sets up a specific configuration, one or more test cases using
-       this configuration, and a cleanup function which restores the
-       configuration. A conf case is specified in a test specification
-       either like this:<c>{conf,InitFunc,ListOfCases,CleanupFunc}</c>,
-       or this: <c>{conf,Properties,InitFunc,ListOfCases,CleanupFunc}</c>
-       </item>
-      <tag><em>datadir</em></tag>
-      <item>Data directory for a test suite. This directory contains
-       any files used by the test suite, e.g. additional erlang
-       modules, c code or data files. If the data directory contains
-       code which must be compiled before the test suite is run, it
-       should also contain a makefile source called Makefile.src
-       defining how to compile.
-      </item>
-      <tag><em>documentation clause</em></tag>
-      <item>One of the function clauses in a test case. This clause
-       shall return a list of strings describing what the test case
-       tests.
-      </item>
-      <tag><em>execution clause</em></tag>
-      <item>One of the function clauses in a test case. This clause
-       implements the actual test case, i.e. calls the functions that
-       shall be tested and checks results. The clause shall crash if it
-       fails.
-      </item>
-      <tag><em>major log file</em></tag>
-      <item>This is the test suites log file.
-      </item>
-      <tag><em>Makefile.src</em></tag>
-      <item>This file is used by the test server framework to generate
-       a makefile for a datadir. It contains some special characters
-       which are replaced according to the platform currently tested.
-      </item>
-      <tag><em>minor log file</em></tag>
-      <item>This is a separate log file for each test case.
-      </item>
-      <tag><em>privdir</em></tag>
-      <item>Private directory for a test suite. This directory should
-       be used when the test suite needs to write to files.
-      </item>
-      <tag><em>skip case</em></tag>
-      <item>A test case which shall be skipped.
-      </item>
-      <tag><em>specification clause</em></tag>
-      <item>One of the function clauses in a test case. This clause
-       shall return an empty list, a test specification or
-      <c>{skip,Reason}</c>. If an empty list is returned, it means
-       that the test case shall be executed, and so it must also have
-       an execution clause.
-      </item>
-      <tag><em>test case</em></tag>
-      <item>A single test included in a test suite. Typically it tests
-       one function in a module or application. A test case is
-       implemented as a function in a test suite module. The function
-       can have three clauses, the documentation-, specification- and
-       execution clause.
-      </item>
-      <tag><em>test specification</em></tag>
-      <item>A specification of which test suites and test cases to
-       run. There can be test specifications on three different levels
-       in a test. The top level is a test specification file which
-       roughly specifies what to test for a whole application. Then
-       there is a test specification for each test suite returned from
-       the <c>all(suite)</c> function in the suite. And there can also
-       be a test specification returned from the specification clause
-       of a test case.
-      </item>
-      <tag><em>test specification file</em></tag>
-      <item>This is a text file containing the test specification for
-       an application. The file has the extension ".spec" or
-       ".spec.Platform", where Platform is e.g. "vxworks".
-      </item>
-      <tag><em>test suite</em></tag>
-      <item>An erlang module containing a collection of test cases for
-       a specific application or module.
-      </item>
-      <tag><em>topcase</em></tag>
-      <item>The first "command" in a test specification file. This
-       command contains the test specification, like this:
-      <c>{topcase,TestSpecification}</c></item>

-	    When generating Makefile from Makefile.src,
-	    ts_lib:get_arg/4 earlier removed all spaces in the
-	    extracted argument. The code was probably meant for
-	    removing leading and trailing spaces only, and is now
-	    corrected to do so.</p>

-	    The status of an aborted test due to test suite

-	    application. A test category is represented by a CT test
-	    specification and defines an arbitrary subset of existing
-	    test suites, groups and cases. Examples of test
-	    categories are 'smoke' (smoke tests) and 'bench'
-	    (benchmarks). (Call ts:help() for more info). Also,
-	    functions for reading terms from the current test
-	    specification during test, ct:get_testspec_terms/0 and
-	    ct:get_testspec_terms/1, have been implemented.</p>

-	    If the last expression in a test case causes a timetrap
-	    timeout, the stack trace is ignored and not printed to
-	    the test case log file. This happens because the
-	    {Suite,TestCase,Line} info is not available in the stack
-	    trace in this scenario, due to tail call elimination.
-	    Common Test has been modified to handle this situation by
-	    inserting a {Suite,TestCase,last_expr} tuple in the
-	    correct place and printing the stack trace as expected.</p>

-	    The source code to html code generator in Test Server
-	    (and Common Test) would fail to generate anchors in the
-	    html code for functions with non-expandable macros,
-	    resulting in bad html links to such functions. This
-	    correction lets the code generator ignore macros that
-	    can't be expanded (i.e. not pre-process them), so that
-	    correct anchors will always be produced.</p>

-	    The mechanism for running code cover analysis with
-	    common_test has been improved. Earlier, if a test run
-	    consisted of multiple tests, cover would be started and
-	    stopped for each test. This would give "intermediate"
-	    cover logs available from the "Coverage log" link on the
-	    test suite result pages. To accumulate cover data over
-	    all tests, the 'export' option had to be used in the
-	    cover spec file. This was not well documented, and the
-	    functionality was quite confusing.</p>
-          <p>
-	    Using the 'nodes' option in the cover spec file would
-	    fail when the test run consisted of multiple tests, since
-	    the specified nodes would only be included in the cover
-	    analysis of the first test.</p>
-          <p>
-	    The repeated compilation and analysis of the same modules
-	    was also very time consuming.</p>
-          <p>
-	    To overcome these problems, ct will now only cover
-	    compile and analyze modules once per test run, i.e. once
-	    for each cover spec file. The log file is available via a
-	    new button on the top level index page. The old "Coverage
-	    log" links on the test suite result pages still exist,
-	    but they all point to the same log containing the
-	    accumulated result.</p>

-	    <p>The way Common Test handles skipping of test cases has
-	    been updated. In previous versions, returning
-	    <c>{skip,Reason}</c> from a configuration function (such
-	    as init_per_suite or init_per_group), resulted in all
-	    affected test cases getting skipped with status
-	    <c>auto_skipped</c>. This was inappropriate, since this
-	    status is supposed to be used to inform that Common Test
-	    has taken the initiative to skip something (e.g. a test
-	    case group if init_per_group failed). Therefore, in this
-	    version of Common Test, whenever the user skips a suite,
-	    group, or individual test case (by means of a
-	    configuration function or test specification term), the
-	    affected test cases get the status <c>user_skipped</c>
-	    instead.</p> <p>This update has meant a few changes that
-	    may affect Common Test users in various ways:</p> <list>
-	    <item>The test results and statistics will be affected,
-	    which is important to know when running regression tests
-	    and comparing results to previous test runs.</item>
-	    <item>Users that read or parse the textual log file
-	    <c>suite.log</c> will notice that an auto skipped
-	    function is now reported as <c>auto_skipped</c> rather
-	    than <c>skipped</c> as before.</item> <item>When
-	    <c>require</c> fails in an info function (such as suite/0
-	    or group/1), all affected configuration functions and
-	    test cases are marked as <c>auto_skipped</c>.</item>
-	    <item>If Common Test detects an error in the test suite
-	    (such as e.g. an invalid all/0 function), all affected
-	    configuration functions and test cases are marked as
-	    <c>auto_skipped</c>.</item> <item>If a repeated test run
-	    session reaches a deadline with <c>force_stop</c>
-	    enabled, all remaining test cases are marked as
-	    <c>auto_skipped</c> rather than <c>user_skipped</c> as
-	    before.</item> <item>The event messages that Common Test
-	    generates during test runs have been affected by this
-	    update. For details see OTP-11524.</item> </list>

-	    Test Server installed an error handler (test_server_h)

-	    The unicode update of test_server for R16A introduced a
-	    few potential errors when logging to files. Sometimes ~tp
-	    or ~ts was used for formatting also when writing to files
-	    that were not opened with the {encoding,utf8} option. If
-	    then the argument contained unicode characters above 255,
-	    the file descriptor would crash. This has been corrected
-	    by the following modifications:</p> <list> <item> Since the
-	    'unexpected_io' log file is used only when the test case
-	    HTML file is not available (e.g. between test cases),
-	    this file is now also a HTML file and as other
-	    test_server HTML logs it is always UTF-8 encoded </item>
-	    <item> Since it is possible to change which information
-	    is going to which log file (with
-	    test_server_ctrl:set_levels/3), we do not have full
-	    control over which information is written to which file.
-	    This means that any printout could be written to the
-	    'major' log file (suite.log), which was earlier encoded
-	    as latin1. To avoid crashing this file descriptor due to
-	    unicode strings, the 'major' log file is now also encoded
-	    in UTF-8 (possible incopatibility). </item> <item> The
-	    cross_cover.info file is no longer a text file which can
-	    be read with file:consult/1, instead it is written as a
-	    pure binary file using term_to_binary when writing and
-	    binary_to_term when reading. </item> <item> The encoding
-	    of the file named 'last_name', which only content is the
-	    path to the last run.&lt;timestamp&gt; directory, is now
-	    dependent on the file name mode of the VM. If file names
-	    are expected to be unicode, then the 'last_name' file is
-	    UTF-8 encoded, else it is latin1 encoded. </item> </list>
-          <p>
-	    Also, ~tp has been changed back to ~p unless it is
-	    somehow likely that the argument includes strings. It is
-	    not obvious that this is the correct thing to do, but
-	    some decission had to be taken...</p>

-	    <p>In test_server, the same process would supervise the

-	    server) for the test case. Furthermore, when running
-	    parallel test cases, new temporary supervisor/group
-	    leader processes were spawned and the process that was
-	    group leader for sequential test cases would not be
-	    active. That would lead to several problems:</p>
-	    <p>* Processes started by init_per_suite will inherit the
-	    group leader of the init_per_suite process (and that
-	    group leader would not process IO requests when parallel
-	    test cases was running). If later a parallel test case
-	    caused such a processto print using (for example)
-	    io:format/2, the calling would hang.</p>
-	    <p>* Similarly, if a process was spawned from a parallel
-	    test case, it would inherit the temporary group leader
-	    for that parallel test case. If that spawned process
-	    later - when the group of parallel tests have finished -
-	    attempted to print something, its group leader would be
-	    dead and there would be <c>badarg</c> exception.</p>
-	    <p>Those problems have been solved by having group
-	    leaders separate from the processes that supervises the
-	    test cases, and keeping temporary group leader process
-	    for parallel test cases alive until no more process in
-	    the system use them as group leaders.</p>
-	    <p>Also, a new <c>unexpected_io.log</c> log file
-	    (reachable from the summary page of each test suite) has
-	    been introduced. All unexpected IO will be printed into

-	    versions of the Common Test logging functions, ct:log,

-	    Importance argument added. The Importance value is

-	    A new optional feature has been introduced that enables

-	    the option/flag is 'create_priv_dir' and it can be set to
-	    value 'auto_per_run' (which is the default, existing,
-	    behaviour), or 'auto_per_tc' or 'manual_per_tc'. If
-	    'auto_per_tc' is used, Test Server creates a dedicated
-	    priv_dir automatically for each test case (which can be
-	    very expensive in case of many and/or repeated cases). If
-	    'manual_per_tc' is used, the user needs to create the
-	    priv_dir explicitly by calling the new function
-	    ct:make_priv_dir/0.</p>

-	    Common Test has been updated to handle start options and
-	    test specification terms for test case groups (and test
-	    cases in groups). Also, an option named 'label', has been
-	    added that associates the test run with a name that
-	    Common Test prints in the overview HTML logs.</p>

-	    even if the test case has been terminated explicitly
-	    (with abort_current_testcase/1), or after a timetrap
-	    timeout. Under these circumstances the return value of
-	    end_per_testcase is completely ignored. Therefore the
-	    function will not be able to change the reason for test
-	    case termination by returning {fail,Reason}, nor will it
-	    be able to save data with {save_config,Data}.</p>

-	    Previously, a repeat property of a test case group
-	    specified the number of times the group should be
-	    repeated after the main test run. I.e. {repeat,N} would
-	    case the group to execute 1+N times. To be consistent
-	    with the behaviour of the run_test repeat option, this
-	    has been changed. N now specifies the absolute number of
-	    executions instead.</p>

-	    <p>- Enhanced the menu positioning in the html

-	    <p>- A number of corrections in the generation of man

-	    The conf case in Test Server has been extended with
-	    properties that make it possible to execute test cases in
-	    parallel, in sequence and in shuffled order. It is now
-	    also possible to repeat test cases according to different
-	    criterias. The properties can be combined, making it
-	    possible to e.g. repeat a conf case a certain number of
-	    times and execute the test cases in different (random)
-	    order every time. The properties are specified in a list
-	    in the conf case definition: {conf, Properties, InitCase,
-	    TestCases, EndCase}. The available properties are:
-	    parallel, sequence, shuffle, repeat, repeat_until_all_ok,
-	    repeat_until_any_ok, repeat_until_any_fail,
-	    repeat_until_all_fail.</p>

-	    Test Server is a portable test server for automated
-	    application testing. The server can run test suites on
-	    local or remote targets and log progress and results to
-	    HTML pages. The main purpose of Test Server is to act as
-	    engine inside customized test tools. A callback interface
-	    for such framework applications is provided.</p>

-      <title>Improvements and New Features</title>
-      <list type="bulleted">
-        <item>
-          <p>Added the options <c>cover</c> and <c>cover_details</c>
-            to <c>ts:run</c>. When one of these options is used, 
-            the tested application will be cover compiled
-            before the test is run. The cover compiled code will also
-            be loaded on all slave or peer nodes started with
-            <c>test_server:start_node</c>. When the test is completed
-            coverage data from all nodes is collected and merged, and
-            presented in the coverage log to which there will be a link
-            from the test suite result page (i.e. the one with the 
-            heading "Test suite ... results").</p>
-          <p>The <c>cover_details</c> option will do 
-            <c>cover:analyse_to_file</c> for each cover compiled module,
-            while the <c>cover</c> option only will produce a list of
-            modules and the number of covered/uncovered lines in each
-            module.</p>
-          <p>To make it possible to run all test from a script (like in
-            the OTP daily builds), the following is added:
-            <c>ts:run([all_tests | Options])</c>.</p>
-          <p>This means that e.g. the following is possible:
-            <c>erl -s ts run all_tests batch cover</c>.</p>
-          <p>Note that it is also possible to run tests with cover even 
-            if you don't use <c>ts</c>.
-            See <c>test_server_ctrl:cover/2/3</c>.</p>
-          <p>Own Id: OTP-4703</p>
-        </item>
-        <item>
-          <p>Removed module <c>ts_save.erl</c> and function
-            <c>ts:save/0/1</c><em>(incompatible)</em>.</p>
-          <p>Added config variable <c>ipv6_hosts</c> to
-            <c>ts:install/1</c> and test spec file.</p>
-          <p>No longer removing duplicates of test cases from test spec
-            <em>(incompatible)</em>.</p>
-          <p>Added function <c>test_server:run_on_shielded_node/2</c>.</p>
-          <p>Creation of html files for test suite source does no longer
-            crash if suite contains more than 9999 lines of code.</p>
-          <p>Added functionality for cross cover compilation,
-            i.e. collection of cover data from all tests.</p>
-          <p>Multiplying timetrap times with 10 when running with cover.</p>
-          <p>Added <c>ts:r/3</c> for running tests with cover.</p>
-          <p>*** POTENTIAL INCOMPATIBILITY ***</p>
-          <p>Own Id: OTP-5040</p>

-    <title>Using the test server controller</title>
-    <p>The test server controller provides a low level interface to
-      all the Test Server functionality. It is possible to use this
-      interface directly, but it is recommended to use a framework
-      such as <em>Common Test</em> instead. If no existing framework
-      suits your needs, you could of course build your own 
-      on top of the test server controller. Some information about how 
-      to do this can be found in the section named "Writing you own 
-      test server framework" in the Test Server User's Guide.
-      </p>
-    <p>For information about using the controller directly, please see 
-      all available functions in the reference manual for
-      <c>test_server_ctrl</c>.

-    <title>TEST SUITE SUPPORT FUNCTIONS</title>
-    <p>The following functions are supposed to be used inside a test
-      suite.
-      </p>
-  </section>
-  <funcs>
-    <func>
-      <name>os_type() -> OSType</name>
-      <fsummary>Returns the OS type of the target node</fsummary>
-      <type>

-        <d>This is the same as returned from <c>os:type/0</c></d>
-      </type>
-      <desc>
-        <p>This function is equivalent to <c>os:type/0</c>. It is kept

-    <func>
-      <name>fail()</name>

-      <fsummary>Makes the test case fail.</fsummary>
-      <type>
-        <v>Reason = term()</v>
-        <d>The reason why the test case failed.</d>
-      </type>
-      <desc>
-        <p>This will make the test suite fail with a given reason, or
-          with <c>suite_failed</c> if no reason was given. Use this
-          function if you want to terminate a test case, as this will
-          make it easier to read the log- and HTML files. <c>Reason</c>
-          will appear in the comment field in the HTML log.</p>
-      </desc>
-    </func>
-    <func>
-      <name>timetrap(Timout) -> Handle</name>
-      <fsummary></fsummary>
-      <type>
-        <v>Timeout = integer() | {hours,H} | {minutes,M} | {seconds,S}</v>
-        <v>H = M = S = integer()</v>
-        <v>Pid = pid()</v>
-        <d>The process that is to be timetrapped (<c>self()</c>by default)</d>
-      </type>
-      <desc>
-        <p>Sets up a time trap for the current process. An expired
-          timetrap kills the process with reason
-          <c>timetrap_timeout</c>. The returned handle is to be given
-          as argument to <c>timetrap_cancel</c> before the timetrap
-          expires.  If <c>Timeout</c> is an integer, it is expected to
-          be milliseconds.</p>
-        <note>
-          <p>If the current process is trapping exits, it will not be killed
-            by the exit signal with reason <c>timetrap_timeout</c>.
-            If this happens, the process will be sent an exit signal
-            with reason <c>kill</c> 10 seconds later which will kill the
-            process. Information about the timetrap timeout will in
-            this case not be found in the test logs. However, the
-            error_logger will be sent a warning.</p>
-        </note>
-      </desc>
-    </func>
-    <func>
-      <name>timetrap_cancel(Handle) -> ok</name>
-      <fsummary>Cancels a timetrap.</fsummary>
-      <type>

-        <v>ScaleFactor = integer()</v>
-      </type>
-      <desc>
-        <p>This function returns the scale factor by which all timetraps
-	are scaled. It is normally 1, but can be greater than 1 if
-	the test_server is running <c>cover</c>, using a larger amount of
-	scheduler threads than the amount of logical processors on the
-	system, running under purify, valgrind or in a debug-compiled
-	emulator. The scale factor can be used if you need to scale you
-	own timeouts in test cases with same factor as the test_server
-	uses.</p>
-      </desc>

-        <d>The number of milliseconds to sleep</d>
-      </type>
-      <desc>
-        <p>This function suspends the calling process for at least the
-          supplied number of milliseconds. There are two major reasons
-          why you should use this function instead of
-          <c>timer:sleep</c>, the first being that the module
-          <c>timer</c> may be unavailable at the time the test suite is
-          run, and the second that it also accepts floating point
-          numbers.</p>
-      </desc>
-    </func>
-    <func>
-      <name>adjusted_sleep(MSecs) -> ok</name>
-      <fsummary>Suspens the calling task for a specified time.</fsummary>
-      <type>
-        <v>MSecs = integer() | float() | infinity</v>
-        <d>The default number of milliseconds to sleep</d>
-      </type>
-      <desc>
-        <p>This function suspends the calling process for at least the
-          supplied number of milliseconds. The function behaves the same
-	  way as <c>test_server:sleep/1</c>, only <c>MSecs</c>
-	  will be multiplied by the 'multiply_timetraps' value, if set,
-	  and also automatically scaled up if 'scale_timetraps' is set
-	  to true (which it is by default).</p>
-      </desc>

-    <title>TEST SUITE SUPPORT MACROS</title>
-    <p>There are some macros defined in the <c>test_server.hrl</c>
-      that are quite useful for test suite programmers:
-      </p>
-    <p>The <em>config</em> macro, is used to
-      retrieve information from the <c>Config</c> variable sent to all
-      test cases. It is used with two arguments, where the first is the
-      name of the configuration variable you wish to retrieve, and the
-      second is the <c>Config</c> variable supplied to the test case
-      from the test server.
-      </p>
-    <p>Possible configuration variables include:</p>
-    <list type="bulleted">
-      <item><c>data_dir</c>  - Data file directory.</item>
-      <item><c>priv_dir</c>  - Scratch file directory.</item>
-      <item><c>nodes</c>     - Nodes specified in the spec file</item>
-      <item><c>nodenames</c> - Generated nodenames.</item>
-      <item>Whatever added by conf test cases or
-      <c>init_per_testcase/2</c></item>
-    </list>
-    <p>Examples of the <c>config</c> macro can be seen in the Examples chapter
-      in the user's guide.</p>
-    <p>The <em>line</em> and <em>line_trace</em> macros are deprecated, see
-      below.</p>
-  </section>
-
-  <section>
-    <title>TEST SUITE LINE NUMBERS</title>
-    <p>In the past, ERTS did not produce line numbers when generating
-      stacktraces, test_server was thus unable to provide them when reporting
-      test failures. It had instead two different mecanisms to do it: either by
-      using the <c>line</c> macro or by using the <c>test_server_line</c> parse
-      transform. Both are deprecated and should not be used in new tests
-      anymore.</p>

-  <description>
-    <p><em>Test Server</em> is a portable test server for
-      automated application testing. The server can run test suites
-      and log progress and results to HTML
-      pages. The main purpose of Test Server is to act as engine
-      inside customized test tools. A callback interface for 
-      such framework applications is provided.</p>
-    <p>In brief the test server supports:</p>
-    <list type="bulleted">
-      <item>Running multiple, concurrent test suites</item>
-      <item>Test suites may contain other test suites, in a tree fashion</item>
-      <item>Logging of the events in a test suite, on both suite and case levels</item>
-      <item>HTML presentation of test suite results</item>
-      <item>HTML presentation of test suite code</item>
-      <item>Support for test suite authors, e.g. start/stop slave nodes</item>
-      <item>Call trace on target and slave nodes</item>
-    </list>
-    <p>For information about how to write test cases and test suites,
-      please see the Test Server User's Guide and the reference
-      manual for the <c>test_server</c> module.
-      </p>
-    <p><em>Common Test</em> is an existing test tool application based on the

-  <description>
-    <p>The <c>test_server_ctrl</c> module provides a low level
-      interface to the Test Server. This interface is normally
-      not used directly by the tester, but through a framework built 
-      on top of <c>test_server_ctrl</c>.
-      </p>
-    <p>Common Test is such a framework, well suited for automated
-      black box testing of target systems of any kind (not necessarily
-      implemented in Erlang). Common Test is also a very useful tool for
-      white box testing Erlang programs and OTP applications. 
-      Please see the Common Test User's Guide and reference manual for 
-      more information.
-      </p>
-    <p>If you want to write your own framework, some more information
-      can be found in the chapter "Writing your own test server
-      framework" in the Test Server User's Guide. Details about the
-      interface provided by <c>test_server_ctrl</c> follows below.

-  <section>
-    <title>Test structure</title>
-    <p>A test consists of a set of test cases. Each test case is
-      implemented as an erlang function. An erlang module implementing
-      one or more test cases is called a test suite.
-      </p>
-  </section>
-
-  <section>
-    <title>Test specifications</title>
-    <p>A test specification is a specification of which test suites
-      and test cases to run and which to skip. A test specification can
-      also group several test cases into conf cases with init and
-      cleanup functions (see section about configuration cases
-      below). In a test there can be test specifications on three
-      different levels:
-      </p>
-    <p>The top level is a test specification file which roughly
-      specifies what to test for a whole application. The test
-      specification in such a file is encapsulated in a topcase
-      command. 
-      </p>
-    <p>Then there is a test specification for each test suite,
-      specifying which test cases to run within the suite. The test
-      specification for a test suite is returned from the
-      <c>all(suite)</c> function in the test suite module. 
-      </p>
-    <p>And finally there can be a test specification per test case,
-      specifying sub test cases to run. The test specification for a
-      test case is returned from the specification clause of the test
-      case.
-      </p>
-    <p>When a test starts, the total test specification is built in a
-      tree fashion, starting from the top level test specification.
-      </p>
-    <p>The following are the valid elements of a test
-      specification. The specification can be one of these elements or a
-      list with any combination of the elements:
-      </p>
-    <taglist>
-      <tag><c>{Mod, Case}</c></tag>
-      <item>This specifies the test case Mod:Case/1
-      </item>
-      <tag><c>{dir, Dir}</c></tag>
-      <item>This specifies all modules <c>*_SUITE</c> in the directory
-      <c>Dir</c></item>
-      <tag><c>{dir, Dir, Pattern}</c></tag>
-      <item>This specifies all modules <c>Pattern*</c> in the
-       directory <c>Dir</c></item>
-      <tag><c>{conf, Init, TestSpec, Fin}</c></tag>
-      <item>This is a configuration case. In a test specification
-       file, <c>Init</c> and <c>Fin</c> must be
-      <c>{Mod,Func}</c>. Inside a module they can also be just
-      <c>Func</c>. See the section named Configuration Cases below for
-       more information about this.
-      </item>
-      <tag><c>{conf, Properties, Init, TestSpec, Fin}</c></tag>
-      <item>This is a configuration case as explained above, but
-       which also takes a list of execution properties for its group
-       of test cases and nested sub-groups.
-      </item>
-      <tag><c>{make, Init, TestSpec, Fin}</c></tag>
-      <item>This is a special version of a conf case which is only
-       used by the test server framework <c>ts</c>. <c>Init</c> and
-      <c>Fin</c> are make and unmake functions for a data
-       directory. <c>TestSpec</c> is the test specification for the
-       test suite owning the data directory in question. If the make
-       function fails, all tests in the test suite are skipped. The
-       difference between this "make case" and a normal conf case is
-       that for the make case, <c>Init</c> and <c>Fin</c> are given with
-       arguments (<c>{Mod,Func,Args}</c>).
-      </item>
-      <tag><c>Case</c></tag>
-      <item>This can only be used inside a module, i.e. not a test
-       specification file. It specifies the test case
-      <c>CurrentModule:Case</c>.
-      </item>
-    </taglist>
-  </section>
-
-  <section>
-    <title>Test Specification Files</title>
-    <p>A test specification file is a text file containing the top
-      level test specification (a topcase command), and possibly one or
-      more additional commands. A "command" in a test specification file
-      means a key-value tuple ended by a dot-newline sequence.
-      </p>
-    <p>The following commands are valid:
-      </p>
-    <taglist>

-    <title>Configuration cases</title>
-    <p>If a group of test cases need the same initialization, a so called
-      <em>configuration</em> or <em>conf</em> case can be used. A conf
-      case consists of an initialization function, the group of test cases
-      needing this initialization and a cleanup or finalization function.
-      </p>
-    <p>If the init function in a conf case fails or returns
-      <c>{skip,Comment}</c>, the rest of the test cases in the conf case
-      (including the cleanup function) are skipped. If the init function
-      succeeds, the cleanup function will always be called, even if some
-      of the test cases in between failed.
-      </p>
-    <p>Both the init function and the cleanup function in a conf case
-      get the <c>Config</c> parameter as only argument. This parameter
-      can be modified or returned as is. Whatever is returned by the
-      init function is given as <c>Config</c> parameter to the rest of
-      the test cases in the conf case, including the cleanup function.
-      </p>
-    <p>If the <c>Config</c> parameter is changed by the init function,
-      it must be restored by the cleanup function. Whatever is returned
-      by the cleanup function will be given to the next test case called.
-      </p>
-    <p>The optional <c>Properties</c> list can be used to specify
-      execution properties for the test cases and possibly nested
-      sub-groups of the configuration case. The available properties are:</p>
-    <pre>
-      Properties = [parallel | sequence | Shuffle | {RepeatType,N}]
-      Shuffle = shuffle | {shuffle,Seed}
-      Seed = {integer(),integer(),integer()}
-      RepeatType = repeat | repeat_until_all_ok | repeat_until_all_fail |
-                   repeat_until_any_ok | repeat_until_any_fail
-      N = integer() | forever</pre>
-
-    <p>If the <c>parallel</c> property is specified, Test Server will execute
-    all test cases in the group in parallel. If <c>sequence</c> is specified,
-    the cases will be executed in a sequence, meaning if one case fails, all
-    following cases will be skipped. If <c>shuffle</c> is specified, the cases
-    in the group will be executed in random order. The <c>repeat</c> property
-    orders Test Server to repeat execution of the cases in the group a given
-    number of times, or until any, or all, cases fail or succeed.</p>
-
-    <p>Properties may be combined so that e.g. if <c>shuffle</c>, 
-    <c>repeat_until_any_fail</c> and <c>sequence</c> are all specified, the test 
-    cases in the group will be executed repeatedly and in random order until
-    a test case fails, when execution is immediately stopped and the rest of 
-    the cases skipped.</p>
-
-    <p>The properties for a conf case is always printed on the top of the HTML log 
-    for the group's init function. Also, the total execution time for a conf case
-    can be found at the bottom of the log for the group's end function.</p>
-
-    <p>Configuration cases may be nested so that sets of grouped cases can be 
-    configured with the same init- and end functions.</p>
-  </section>
-
-  <section>
-    <title>The parallel property and nested configuration cases</title>
-    <p>If a conf case has a parallel property, its test cases will be spawned
-    simultaneously and get executed in parallel. A test case is not allowed
-    to execute in parallel with the end function however, which means
-    that the time it takes to execute a set of parallel cases is equal to the
-    execution time of the slowest test case in the group. A negative side
-    effect of running test cases in parallel is that the HTML summary pages
-    are not updated with links to the individual test case logs until the 
-    end function for the conf case has finished.</p>
-
-    <p>A conf case nested under a parallel conf case will start executing in 
-    parallel with previous (parallel) test cases (no matter what properties the 
-    nested conf case has). Since, however, test cases are never executed in 
-    parallel with the init- or the end function of the same conf case, it's 
-    only after a nested group of cases has finished that any remaining parallel 
-    cases in the previous conf case get spawned.</p>
-  </section>
-
-  <section>
-    <title>Repeated execution of test cases</title>
-    <marker id="repeated_cases"></marker>
-    <p>A conf case may be repeated a certain number of times
-    (specified by an integer) or indefinitely (specified by <c>forever</c>).
-    The repetition may also be stopped prematurely if any or all cases
-    fail or succeed, i.e. if the property <c>repeat_until_any_fail</c>,
-    <c>repeat_until_any_ok</c>, <c>repeat_until_all_fail</c>, or 
-    <c>repeat_until_all_ok</c> is used. If the basic <c>repeat</c>
-    property is used, status of test cases is irrelevant for the repeat 
-    operation.</p>
-    
-    <p>It is possible to return the status of a conf case (ok or
-    failed), to affect the execution of the conf case on the level above. 
-    This is accomplished by, in the end function, looking up the value
-    of <c>tc_group_properties</c> in the <c>Config</c> list and checking the
-    result of the finished test cases. If status <c>failed</c> should be
-    returned from the conf case as a result, the end function should return
-    the value <c>{return_group_result,failed}</c>. The status of a nested conf
-    case is taken into account by Test Server when deciding if execution
-    should be repeated or not (unless the basic <c>repeat</c> property is used).</p>
-
-    <p>The <c>tc_group_properties</c> value is a list of status tuples, 
-    each with the key <c>ok</c>, <c>skipped</c> and <c>failed</c>. The
-    value of a status tuple is a list containing names of test cases 
-    that have been executed with the corresponding status as result.</p>
-
-    <p>Here's an example of how to return the status from a conf case:</p>
-    <pre>
-      conf_end_function(Config) ->
-          Status = ?config(tc_group_result, Config),
-          case proplists:get_value(failed, Status) of
-              [] ->                                   % no failed cases 
-	          {return_group_result,ok};
-	      _Failed ->                              % one or more failed
-	          {return_group_result,failed}
-          end.</pre>
-
-    <p>It is also possible in the end function to check the status of
-    a nested conf case (maybe to determine what status the current conf case should
-    return). This is as simple as illustrated in the example above, only the
-    name of the end function of the nested conf case is stored in a tuple 
-    <c>{group_result,EndFunc}</c>, which can be searched for in the status lists. 
-    Example:</p>
-    <pre>
-      conf_end_function_X(Config) ->
-          Status = ?config(tc_group_result, Config),
-          Failed = proplists:get_value(failed, Status),
-          case lists:member({group_result,conf_end_function_Y}, Failed) of
-	        true ->
-		    {return_group_result,failed};
-                false ->                                                    
-	            {return_group_result,ok}
-          end; 
-      ...</pre>
-
-    <note><p>When a conf case is repeated, the init- and end functions
-      are also always called with each repetition.</p></note>
-  </section>
-
-  <section>
-    <title>Shuffled test case order</title>
-    <p>The order that test cases in a conf case are executed, is under normal
-    circumstances the same as the order defined in the test specification.
-    With the <c>shuffle</c> property set, however, Test Server will instead 
-    execute the test cases in random order.</p>
-
-    <p>The user may provide a seed value (a tuple of three integers) with
-    the shuffle property: <c>{shuffle,Seed}</c>. This way, the same shuffling
-    order can be created every time the conf case is executed. If no seed value
-    is given, Test Server creates a "random" seed for the shuffling operation 
-    (using the return value of <c>erlang:now()</c>). The seed value is always
-    printed to the log file of the init function so that it can be used to
-    recreate the same execution order in subsequent test runs.</p>
-
-    <note><p>If execution of a conf case with shuffled test cases is repeated,
-      the seed will not be reset in between turns.</p></note>
-
-    <p>If a nested conf case is specified in a conf case with a <c>shuffle</c> 
-    property, the execution order of the nested cases in relation to the test cases 
-    (and other conf cases) is also random. The order of the test cases in the nested
-    conf case is however not random (unless, of course, this one also has a
-    <c>shuffle</c> property).</p>
-  </section>
-
-  <section>
-    <title>Skipping test cases</title>
-    <p>It is possible to skip certain test cases, for example if you
-      know beforehand that a specific test case fails. This might be
-      functionality which isn't yet implemented, a bug that is known but
-      not yet fixed or some functionality which doesn't work or isn't
-      applicable on a specific platform.
-      </p>
-    <p>There are several different ways to state that a test case
-      should be skipped:</p>
-    <list type="bulleted">
-      <item>Using the <c>{skip,What}</c> command in a test
-       specification file
-      </item>
-      <item>Returning <c>{skip,Reason}</c> from the
-      <c>init_per_testcase/2</c> function
-      </item>
-      <item>Returning <c>{skip,Reason}</c> from the specification
-       clause of the test case
-      </item>
-      <item>Returning <c>{skip,Reason}</c> from the execution clause
-       of the test case
-      </item>
-    </list>
-    <p>The latter of course means that the execution clause is
-      actually called, so the author must make sure that the test case
-      is not run. For more information about the different clauses in a
-      test case, see the chapter about writing test cases.
-      </p>
-    <p>When a test case is skipped, it will be noted as <c>SKIPPED</c>
-      in the HTML log.

-  <modulesummary>Test Server Framework for testing OTP</modulesummary>
-  <description>
-    <p>This is a framework for testing OTP. The <c>ts</c> module
-      implements the interface to all the functionality in the
-      framework.
-      </p>
-    <p>The framework is built on top of the Test Server Controller,
-      <c>test_server_ctrl</c>, and provides a high level operator
-      interface. The main features added by the framework are:
-      </p>
-    <list type="bulleted">
-      <item>Automatic compilation of test suites and data directories
-      </item>
-      <item>Collection of files in central directories and creation of
-       additional HTML pages for better overview.
-      </item>
-      <item>Single command interface for running all available tests
-      </item>
-      <item>Spawns a new node with correct parameters before starting
-       the test server
-      </item>
-      <item>Atomatically creates the parameter file needed when
-       running tests on remote target
-      </item>
-    </list>
-    <p>More information about the Test Server Framework and how to run
-      test cases can be found in the Test Server User's Guide.
-      </p>
-    <p>For writing you own test server framework, please turn to the
-      reference manual for the Test Server Controller and chapter named
-      "Writing your own test server framework" in the Test Server User's
-      Guide.
-      </p>
-      <p>SETUP</p>
-    <p>To be able to run <c>ts</c>, you must first `install'
-        <c>ts</c> for the current environment. This is done by calling
-        <c>ts:install/0/1/2</c>. A file called `variables' is created
-        and used by <c>ts</c> when running test suites. It is not
-        recommended to edit this file, but it is possible to alter if
-        <c>ts</c> gets the wrong idea about your environment.
-        </p>
-    <p><c>ts:install/0</c> is used if the target platform is the
-        same as the controller host, i.e. if you run on "local target"
-        and no options are needed. Then running <c>ts:install/0</c> <c>ts</c>
-	will run an autoconf script for your current
-        environment and set up the necessary variables needed by the
-        test suites.
-        </p>
-    <p><c>ts:install/1</c> or <c>ts:install/2</c> is used if the
-        target platform is different from the controller host, i.e. if
-        you run on "remote target" or if special options are required
-        for your system.
-        </p>
-      <p>See the reference manual for detailed information about
-        <c>ts:install/0/1/2</c>.
-        </p>
-    <p>Some of the common variables in the 'variables' file are
-        described below. Do not make any assumptions as of what is found
-        in this file, as it may change at any time.
-        </p>
-    <list>
-        <item><c>longnames</c><br></br>
-        Set to true if the system is using fully qualified
-         nodenames.
-        </item>
-        <item><c>platform_id</c><br></br>
-        This is the currently installed platform identification
-         string.
-        </item>
-        <item><c>platform_filename</c><br></br>
-        This is the name used to create the final save directory
-         for test runs.
-        </item>
-        <item><c>platform_label</c><br></br>
-        This is the string presented in the generated test
-         results index page.
-        </item>
-        <item><c>rsh_name</c><br></br>
-        This is the rsh program to use when starting slave or
-         peer nodes on a remote host.
-        </item>
-        <item><c>erl_flags</c><br></br>
-        Compile time flags used when compiling test suites.
-        </item>
-        <item><c>erl_release</c><br></br>
-        The Erlang/OTP release being tested.

-        The emulator being tested (e.g. beam)
-        </item>
-        <item><c>'CPU'</c><br></br>
-        The CPU in the machine running the tests, e.g. sparc.
-        </item>
-        <item><c>target_host</c><br></br>
-        The target host name
-        </item>
-        <item><c>os</c><br></br>
-        The target operating system, e.g. solaris2.8

-        </item>
-      </list>
-      <p>RUNNING TESTS</p>
-      <p>After installing <c>ts</c>, you can run your test with the
-        <c>ts:run/0/1/2/3/4</c> functions. These functions, however,
-        require a special directory structure to be able to find your
-        test suites. Both the test server and all tests must be located
-        under your $TESTROOT directory. The test server implementation
-        shall be located in the directory <c>$TESTROOT/test_server</c>
-        and for each application there must be a directory named
-        <c><![CDATA[$TESTROOT/<application>_test]]></c> containing the .spec file
-        and all test suites and data directories for the
-        application. Note that there shall only be one .spec file for
-        each application.
-        </p>
-      <p><c>$TESTROOT/test_server</c> must be the current directory
-        when calling the <c>ts:run/*</c> function.
-        </p>
-      <p>All available tests can be found with <c>ts:tests()</c>. This
-        will list all applications for which a test specification file
-        <c><![CDATA[../<application>_test/<application>.spec]]></c> can be found.
-        </p>
-      <p>To run all these tests, use <c>ts:run()</c>.
-        </p>
-      <p>To run one or some of the tests, use <c>ts:run(Tests)</c>,
-        where <c>Tests</c> is the name of the application you want to
-        test, or a list of such names.
-        </p>
-      <p>To run one test suite within a test, use
-        <c>ts:run(Test,Suite)</c>.
-        </p>
-      <p>To run one test case within a suite, use
-        <c>ts:run(Test,Suite,Case)</c></p>
-      <p>To all these functions, you can also add a list of
-        options. Please turn to the reference manual for the <c>ts</c>
-        module to see the valid options to use.
-        </p>
-      <p>The function <c>ts:help()</c> displays some simple help for
-        the functions in <c>ts</c>. Use this for quick reference.
-        </p>
-      <p>LOG FILES</p>
-      <p>As the execution of the test suites go on, events are logged in

-      <item>Case related information is sent to the minor log file.</item>
-      <item>The HTML log file gets updated with test results.</item>
-    </list>
-    <p>Typically the operator, who may run hundreds or thousands of
-      test cases, doesn't want to fill the screen with details
-      about/from the specific test cases. By default, the operator will
-      only see:

-    <list type="bulleted">
-      <item>A confirmation that the test has started.
-      </item>
-      <item>A small note about each failed test case.

-      <item>A summary of all the run test cases.

-    </list>
-    <p>This is enough for the operator to know, and if he wants to dig

-      following the links in the HTML presentation to take a look in the
-      major or minor log files.
-      </p>
-    <p>A detailed report of the entire test suite is stored in the
-      major logfile, the exact reason for failure, time spent etc.
-      </p>
-    <p>The HTML log file is a summary of the major log file, but gives
-      a much better overview of the test run. It also has links to every
-      test case's log file for quick viewing with a HTML browser.
-      </p>
-    <p>The minor log file contain full details of every single test
-      case, each one in a separate file. This way the files should be
-      easy to compare with previous test runs, even if the set of test
-      cases change.
-      </p>
-    <p>Which information that goes where is user configurable via the
-      test server controller. Three threshold values determine what
-      comes out on screen, and in the major or minor log files. The
-      contents that goes to the HTML log file is fixed, and cannot be
-      altered.

-    <title>Makfile.src in Data Directory</title>
-    <p>If a data directory contains code which must be compiled before
-      the test suite is run, a makefile source called
-      <c>Makefile.src</c> can be placed in the data directory. This file
-      will be converted to a valid makefile by <c>ts:run/0/1/2/3/4</c>.
-      </p>
-    <p>The reason for generating the makefile is that you can use
-      variables from the <c>variables</c> file which was generated by
-      <c>ts:install/0/1/2</c>. All occurrences of <c>@Key@</c> in
-      <c>Makefile.src</c> is substituted by the <c>Value</c> from
-      <c>{Key,Value}</c> found in the <c>variables</c> file. Example:
-      </p>
-    <p>Cut from <c>variables</c>:</p>
-    <code type="none">
-    ...
-    {'EMULATOR',"beam"}.
-    {'CFLAGS',"-g -O2"}.
-    {'LD',"$(CC) $(CFLAGS)"}.
-    {'CC',"gcc"}.
-    ...
-    </code>
-    <p><c>Makefile.src</c> for compiling erlang code could look

-           erlc $(EFLAGS) ordsets1.erl
-    </code>
-    <p><c>Makefile.src</c> for compiling c code could look

-    <title>Goals</title>
-    <p>It's not possible to prove that a program is correct by
-      testing. On the contrary, it has been formally proven that it is
-      impossible to prove programs in general by testing. Theoretical
-      program proofs or plain examination of code may be viable options
-      for those that wish to certify that a program is correct. The test
-      server, as it is based on testing, cannot be used for
-      certification. Its intended use is instead to (cost effectively)
-      <em>find bugs</em>. A successful test suite is one that reveals a
-      bug. If a test suite results in Ok, then we know very little that
-      we didn't know before.
-      </p>
-  </section>
-
-  <section>
-    <title>What to test?</title>
-    <p>There are many kinds of test suites. Some concentrate on
-      calling every function in the interface to some module or
-      server. Some other do the same, but uses all kinds of illegal
-      parameters, and verifies that the server stays alive and rejects
-      the requests with reasonable error codes. Some test suites
-      simulate an application (typically consisting of a few modules of
-      an application), some try to do tricky requests in general, some
-      test suites even test internal functions.
-      </p>
-    <p>Another interesting category of test suites are the ones that
-      check that fixed bugs don't reoccur. When a bugfix is introduced,
-      a test case that checks for that specific bug should be written
-      and submitted to the affected test suite(s).
-      </p>
-    <p>Aim for finding bugs. Write whatever test that has the highest
-      probability of finding a bug, now or in the future. Concentrate
-      more on the critical parts. Bugs in critical subsystems are a lot
-      more expensive than others.
-      </p>
-    <p>Aim for functionality testing rather than implementation
-      details. Implementation details change quite often, and the test
-      suites should be long lived. Often implementation details differ
-      on different platforms and versions. If implementation details
-      have to be tested, try to factor them out into separate test
-      cases. Later on these test cases may be rewritten, or just
-      skipped.
-      </p>
-    <p>Also, aim for testing everything once, no less, no more. It's
-      not effective having every test case fail just because one
-      function in the interface changed.
-      </p>
-  </section>
-
-  <section>
-    <title>How much to test</title>
-    <p>There is a unix shell script that counts the number of non
-      commented words (lines and characters too) of source code in each
-      application's test directory and divides with the number of such
-      source words in the src directory. This is a measure of how much
-      test code there is.
-      </p>
-    <p>There has been much debate over how much test code, compared to
-      production code, should be written in a project. More test code
-      finds more bugs, but test code needs to be maintained just like
-      the production code, and it's expensive to write it in the first
-      place. In several articles from relatively mature software
-      organizations that I have read, the amount of test code has been
-      about the same as the production code.  </p>
-    <p>In OTP, at the time of
-      writing, few applications come even close to this, some have no
-      test code at all.
-      </p>
-
-    <section>
-      <title>Full coverage</title>
-      <p>It is possible to cover compile the modules being tested
-        before running the test suites. Doing so displays which branches
-        of the code that are tested by the test suite, and which are
-        not. Many use this as a measure of a good test suite. When every
-        single line of source code is covered once by the test suite,
-        the test suite is finished.
-        </p>
-      <p>A coverage of 100% still proves nothing, though. It doesn't
-        mean that the code is error free, that everything is tested. For
-        instance, if a function contains a division, it has to be
-        executed at least twice. Once with parameters that cause
-        division by zero, and once with other parameters.
-        </p>
-      <p>High degree of coverage is good of course, it means that no
-        major parts of the code has been left untested. It's another
-        question whether it's cost effective. You're only likely to find
-        50% more bugs when going from 67% to 100% coverage, but the work
-        (cost) is maybe 200% as large, or more, because reaching all of
-        those obscure branches is usually complicated.
-        </p>
-      <p>Again, the reason for testing with the test server is to find
-        bugs, not to create certificates of valid code. Maximizing the
-        number of found bugs per hour probably means not going for 100%
-        coverage. For some module the optimum may be 70%, for some other
-        maybe 250%. 100% shouldn't be a goal in itself.</p>

-      <title>User interface testing</title>
-      <p>It is very difficult to do sensible testing of user
-        interfaces, especially the graphic ones. The test server has
-        some support for capturing the text I/O that goes to the user,
-        but none for graphics. There are several tools on the market
-        that help with this.</p>

-    <title>Introduction</title>
-    <p>The test server controller can be interfaced from the operating
-      system or from within Erlang. The nature of your new framework
-      will decide which interface to use. If you want your framework to
-      start a new node for each test, the operating system interface is
-      very convenient. If your node is already started, going from
-      within Erlang might be a more flexible solution.
-      </p>
-    <p>The two methods are described below.
-      </p>
-  </section>
-
-  <section>
-    <title>Interfacing the test server controller from Erlang</title>
-    <p>Using the test server from Erlang means that you have to start
-      the test server and then add test jobs. Use
-      <c>test_server_ctrl:start/0</c> to start the test server, and
-      <c>test_server_ctrl:stop/0</c> to stop it.
-      </p>
-
-    <section>
-      <title>Adding test jobs</title>
-      <p>There are many commands available for adding test cases to
-        the test server's job queue:        <br></br>
-</p>
-      <list type="bulleted">
-        <item>Single test case        <br></br>
-<c>test_server_ctrl:add_case/2/3</c></item>
-        <item>Multiple test cases from same suite        <br></br>
-<c>test_server_ctrl:add_cases/2/3</c></item>
-        <item>Test suite module or modules        <br></br>
-<c>test_server_ctrl:add_module/1/2</c></item>
-        <item>Some or all test suite modules in a directory        <br></br>
-<c>test_server_ctrl:add_dir/2/3</c></item>
-        <item>Test cases specified in a test specification file        <br></br>
-<c>test_server_ctrl:add_spec/1</c></item>
-      </list>
-      <p>All test suites are given a unique name, which is usually
-        given when the test suite is added to the job queue. In some
-        cases, a default name is used, as in the case when a module is
-        added without a specified name. The test job name is used to
-        store logfiles, which are stored in the `name.logs' directory
-        under the current directory.
-        </p>
-      <p>See the reference manual for details about the functions for
-        adding test jobs.
-        </p>
-    </section>
-  </section>
-
-  <section>
-    <title>Interfacing the test server controller from the operating system.</title>
-    <p>The function <c>run_test/1</c> is your interface in the test
-      server controller if you wish to use it from the operating
-      system. You simply start an erlang shell and invoke this function
-      with the <c>-s</c> option. <c>run_test/1</c> starts the test
-      server, runs the test specified by the command line and stops the
-      test server. The argument to <c>run_test/1</c> is a list of
-      command line flags, typically
-      <c>['KEY1', Value1, 'KEY2', Value2, ...]</c>. 
-      The valid command line flags are listed in the reference manual
-      for <c>test_server_ctrl</c>.
-      </p>
-    <p>A typical command line may look like this      <br></br>
-<c>erl -noshell -s test_server_ctrl run_test KEY1 Value1 KEY2 Value2 ... -s erlang halt</c></p>
-    <p>Or make an alias (this is for unix/tcsh)      <br></br>
-<c>alias erl_test 'erl -noshell -s test_server_ctrl run_test \!* -s erlang halt'</c></p>
-    <p>And then use it like this      <br></br>
-<c>erl_test KEY1 Value1 KEY2 Value2 ...</c>      <br></br>
-</p>
-
-    <section>
-      <title>An Example</title>
-      <p>An example of starting a test run from the command line        <br></br>
-</p>
-      <p><c>erl -name test_srv -noshell -rsh /home/super/otp/bin/ctrsh </c>        <br></br>
-<c>-pa /clearcase/otp/erts/lib/kernel/test </c>        <br></br>
-<c>-boot start_sasl -sasl errlog_type error </c>        <br></br>
-<c>-s test_server_ctrl run_test SPEC kernel.spec -s erlang halt</c>        <br></br>
-</p>
-    </section>

-  <section>
-    <title>Framework callback functions</title>
-    <p>By defining the environment variable
-      <c>TEST_SERVER_FRAMEWORK</c> to a module name, the framework
-      callback functions can be used. The framework callback functions
-      are called by the test server in order let the framework interact
-      with the execution of the tests and to keep the framework upto
-      date with information about the test progress.
-      </p>
-    <p>The framework callback functions are described in the reference
-      manual for <c>test_server_ctrl</c>.
-      </p>
-    <p>Note that this topic is in an early stage of development, and
-      changes might occur.
-      </p>
-  </section>
-
-  <section>
-    <title>Other concerns</title>
-    <p>Some things to think about when writing you own test server
-      framework:
-      </p>
-    <list type="bulleted">
-      <item><c>emulator version</c> - Make sure that the intended
-       version of the emulator is started.
-      </item>
-      <item><c>operating system path</c> - If test cases use port
-       programs, make sure the paths are correct.
-      </item>
-      <item><c>recompilation</c> - Make sure all test suites are fresh
-       compiled.
-      </item>
-      <item><c>test_server.hrl</c> - Make sure the
-      <c>test_server.hrl</c> file is in the include path when
-       compiling test suites.
-      </item>
-      <item><c>running applications</c> - Some test suites require
-       some applications to be running (e.g. sasl). Make sure they are
-       started.
-      </item>
-    </list>

-    <title>Support for test suite authors</title>
-    <p>The <c>test_server</c> module provides some useful functions
-      to support the test suite author. This includes:
-      </p>
-    <list type="bulleted">
-      <item>Starting and stopping slave or peer nodes</item>
-      <item>Capturing and checking stdout output</item>

-      <item>Checking that a function crashes</item>
-      <item>Checking that a function succeeds at least m out of n times</item>
-      <item>Checking .app files</item>
-    </list>
-    <p>Please turn to the reference manual for the <c>test_server</c>
-      module for details about these functions.
-      </p>
-  </section>
-
-  <section>
-    <title>Test suites</title>
-    <p>A test suite is an ordinary Erlang module that contains test
-      cases. It's recommended that the module has a name on the form
-      *_SUITE.erl. Otherwise, the directory function will not find the
-      modules (by default).
-      </p>
-    <p>For some of the test server support, the test server include
-      file <c>test_server.hrl</c> must be included. Never include it
-      with the full path, for portability reasons. Use the compiler 
-      include directive instead.
-      </p>
-    <p>The special function <c>all(suite)</c> in each module is called
-      to get the test specification for that module. The function
-      typically returns a list of test cases in that module, but any
-      test specification could be returned. Please see the chapter
-      about test specifications for details about this.
-      </p>
-  </section>
-
-  <section>
-    <title>Init per test case</title>
-    <p>In each test suite module, the functions
-      <c>init_per_testcase/2</c> and <c>end_per_testcase/2</c> must be
-      implemented.
-      </p>
-    <p><c>init_per_testcase</c> is called before each test case in the
-      test suite, giving a (limited) possibility for initialization.
-      </p>
-    <p><c>end_per_testcase/2</c> is called after each test case is
-      completed, giving a possibility to clean up.
-      </p>
-    <p>The first argument to these functions is the name of the test
-      case. This can be used to do individual initialization and cleanup for
-      each test cases.
-      </p>
-    <p>The second argument is a list of tuples called
-      <c>Config</c>. The first element in a <c>Config</c> tuple
-      should be an atom - a key value to be used for searching. 
-      <c>init_per_testcase/2</c> may modify the <c>Config</c>
-      parameter or just return it as is. Whatever is retuned by
-      <c>init_per_testcase/2</c> is given as <c>Config</c> parameter to
-      the test case itself.
-      </p>
-    <p>The return value of <c>end_per_testcase/2</c> is ignored by the
-      test server.
-      </p>
-  </section>
-
-  <section>
-    <title>Test cases</title>
-    <p>The smallest unit that the test server is concerned with is a
-      test case. Each test case can in turn test many things, for
-      example make several calls to the same interface function with
-      different parameters.
-      </p>
-    <p>It is possible to put many or few tests into each test
-      case. How many things each test case tests is up to the author,
-      but here are some things to keep in mind.
-      </p>
-    <p>Very small test cases often leads to more code, since
-      initialization has to be duplicated. Larger code, especially with
-      a lot of duplication, increases maintenance and reduces
-      readability.
-      </p>
-    <p>Larger test cases make it harder to tell what went wrong if it
-      fails, and force us to skip larger portions of test code if a
-      specific part fails. These effects are accentuated when running on
-      multiple platforms because test cases often have to be skipped.
-      </p>
-    <p>A test case generally consists of three parts, the
-      documentation part, the specification part and the execution
-      part. These are implemented as three clauses of the same function.
-      </p>
-    <p>The documentation clause matches the argument '<c>doc</c>' and
-      returns a list for strings describing what the test case tests.
-      </p>
-    <p>The specification clause matches the argument '<c>suite</c>'
-      and returns the test specification for this particular test
-      case. If the test specification is an empty list, this indicates
-      that the test case is a leaf test case, i.e. one to be executed.
-      </p>
-    <p>The execution clause implements the actual test case. It takes
-      one argument, <c>Config</c>, which contain configuration
-      information like <c>data_dir</c> and <c>priv_dir</c>. See <seealso marker="#data_priv_dir">Data and Private Directories</seealso> for
-      more information about these.
-      </p>
-    <p>The <c>Config</c> variable can also contain the
-      <c>nodenames</c> key, if requested by the <c>require_nodenames</c>
-      command in the test suite specification file. All <c>Config</c>
-      items should be extracted using the <c>?config</c> macro. This is
-      to ensure future compatibility if the <c>Config</c> format
-      changes. See the reference manual for <c>test_server</c> for
-      details about this macro.
-      </p>
-    <p>If the execution clause crashes or exits, it is considered a
-      failure. If it returns <c>{skip,Reason}</c>, the test case is
-      considered skipped. If it returns <c>{comment,String}</c>,
-      the string will be added in the 'Comment' field on the HTML
-      result page. If the execution clause returns anything else, it is
-      considered a success, unless it is <c>{'EXIT',Reason}</c> or
-      <c>{'EXIT',Pid,Reason}</c> which can't be distinguished from a
-      crash, and thus will be considered a failure.
-      </p>
-  </section>

-  <section>
-    <marker id="data_priv_dir"></marker>
-    <title>Data and Private Directories</title>
-    <p>The data directory (<c>data_dir</c>) is the directory where the test
-      module has its own files needed for the testing. A compiler test
-      case may have source files to feed into the compiler, a release
-      upgrade test case may have some old and new release of
-      something. A graphics test case may have some icons and a test
-      case doing a lot of math with bignums might store the correct
-      answers there. The name of the <c>data_dir</c> is the the name of
-      the test suite and then "_data". For example,
-      <c>"some_path/foo_SUITE.beam"</c> has the data directory
-      <c>"some_path/foo_SUITE_data/"</c>.
-      </p>
-    <p>The <c>priv_dir</c> is the test suite's private directory. This
-      directory should be used when a test case needs to write to
-      files. The name of the private directory is generated by the test
-      server, which also creates the directory.
-      </p>
-    <p><em>Warning:</em> Do not depend on current directory to be
-      writable, or to point to anything in particular. All scratch files
-      are to be written in the <c>priv_dir</c>, and all data files found
-      in <c>data_dir</c>. If the current directory has to be something
-      specific, it must be set with <c>file:set_cwd/1</c>.
-      </p>
-  </section>

-  <section>
-    <title>Execution environment</title>
-    <p>Each time a test case is about to be executed, a new process is
-      created with <c>spawn_link</c>. This is so that the test case will
-      have no dependencies to earlier tests, with respect to process flags,
-      process links, messages in the queue, other processes having registered
-      the process, etc. As little as possible is done to change the initial
-      context of the process (what is created by plain spawn). Here is a
-      list of differences:
-      </p>
-    <list type="bulleted">
-      <item>It has a link to the test server. If this link is removed,
-       the test server will not know when the test case is finished,
-       just wait infinitely.
-      </item>
-      <item>It often holds a few items in the process dictionary, all
-       with names starting with '<c>test_server_</c>'. This is to keep
-       track of if/where a test case fails.
-      </item>
-      <item>There is a top-level catch. All of the test case code is
-       catched, so that the location of a crash can be reported back to
-       the test server. If the test case process is killed by another
-       process (thus the catch code is never executed) the test server
-       is not able to tell where the test case was executing.
-      </item>
-      <item>It has a special group leader implemented by the test
-       server. This way the test server is able to capture the io that
-       the test case provokes. This is also used by some of the test
-       server support functions.
-      </item>
-    </list>
-    <p>There is no time limit for a test case, unless the test case
-      itself imposes such a limit, by calling
-      <c>test_server:timetrap/1</c> for example.  The call can be made
-      in each test case, or in the <c>init_per_testcase/2</c>
-      function. Make sure to call the corresponding
-      <c>test_server:timetrap_cancel/1</c> function as well, e.g in the
-      <c>end_per_testcase/2</c> function, or else the test cases will
-      always fail.
-      </p>

-
-    <section>
-      <title>Introduction</title>
-      <p>To ease the use of Cover there is a web based user interface
-        to Cover called WebCover. WebCover is designed to be started
-        and used via WebTool. It is possible to Cover compile Erlang
-        modules and to generate printable Cover and Call analyses via
-        the web based user interface.</p>
-    </section>
-
-    <section>
-      <title>Start the Web Based User Interface to Cover</title>
-      <p>To start WebCover you can either start WebTool, point a
-        browser to the start page of WebTool and start WebCover from
-        there, or you can use the <c>start_webtool</c> script to start
-        Webtool, WebCover and a browser. See WebTool documentation for
-        further information.</p>
-      <p>Currently WebCover is only compatible
-        with Internet Explorer and Netscape Navigator 4.0 and higher.</p>
-    </section>
-
-    <section>
-      <title>Navigating WebCover</title>

-    <title>Introduction </title>
-    <p>WebTool provides an easy and efficient way to implement web
-      based tools with Erlang/OTP. WebTool configures and starts the
-      webserver and the various web based tools.</p>
-    <p>All tools that shall run under WebTool must have a *.tool
-      file in the code path or in its priv directory. When WebTool
-      starts it searches the code path for such files. For each
-      <c>ebin</c> directory in the path, the <c>priv</c> directory is
-      also searched. The *.tool files contain the configuration data
-      for each web based tool.</p>
-  </section>
-
-  <section>
-    <title>Starting WebTool</title>
-    <p>Start WebTool by calling the function <c>webtool:start/0</c> or
-      <c>webtool:start/2</c>.  If <c>webtool:start/0</c> is used the
-      start page of WebTool is available at
-      <em>http://localhost:8888/</em> or
-      <em>http://127.0.0.1:8888/</em>, and the directory containing
-      the root directory for the webserver, is assumed to be
-      <c><![CDATA[webtool-<vsn>/priv]]></c>.</p>
-    <p>Use <c>webtool:start/2</c> if the default path for the root
-      directory, port, ip-number or server name can not be used. See
-      the Reference Manual for <seealso marker="webtool">webtool</seealso> for more information.</p>
-    <p>WebTool, with the default configuration as in <c>start/0</c>,
-      can also be started with the <c>start_webtool</c> script which
-      is available in the <c>priv</c> directory of the WebTool
-      application. See the Reference Manual for <seealso marker="start_webtool">start_webtool</seealso> for further
-      information about this script. For Windows users, the batch file
-      <c>start_webtool.bat</c> can be used for the same purpose.</p>
-  </section>
-
-  <section>
-    <title>Using WebTool</title>
-    <p>Start WebTool and point the browser to the corresponding URL. 
-      At the top of the page there is a frame with a link named 
-      <em>WebTool</em>. Click that link and a page where it is
-      possible to start the available tools will appear in the main
-      frame.</p>
-  </section>
-
-  <section>
-    <title>Start a web based tool</title>
-    <p>Click on the link labeled <em>WebTool</em> in the topmost  frame,
-      select the checkbox for each tool to start and
-      click on the button labeled <em>Start</em>. A link to each tool
-      that WebTool succeeded to start will appear in the topmost frame.</p>
-  </section>
-
-  <section>
-    <title>Stop a web based tool</title>
-    <p>Click on the link labeled <em>WebTool</em> in the topmost
-      frame. Select <em>Stop Tools</em> in the left frame. Select the
-      checkbox for each tool to stop and click on the button labeled
-      <em>Stop</em>.</p>
-  </section>
-
-  <section>
-    <title>Develop new web based tools</title>
-    <p>WebTool can be used as a framework when developing new web based
-      tools.</p>
-    <p>A web based tool running under WebTool will typically consist of
-      three parts.</p>
-    <list type="bulleted">
-      <item>A *.tool file which defines how WebTool can find the tool's
-       configuration data</item>
-      <item>The Erlang code generating the web interface to the tool (HTML
-       code)</item>
-      <item>The tool itself.</item>
-    </list>
-    <p>In most cases it is a good idea to separate the code for
-      creation of the html-pages and the code for the logic. This
-      increases the readability of the code and the logic might be
-      possible to reuse.</p>
-
-    <section>
-      <title>The *.tool file</title>
-      <p>When WebTool starts it searches the current path for
-        <c>*.tool</c> files to find all available tools. The *.tool
-        file contains a version identifier and a list of tuples which
-        is the configuration data. The version identifier specifies
-        the *.tool file version, i.e. not the version of
-        webtool. Currently the only valid version is "1.2" and the
-        only valid configuration tag is
-        <c>config_func</c>. <c>config_func</c> specifies which
-        function WebTool must call to get further configuration data
-        for the tool. This means that a *.tool file generally must
-        look like this:</p>
-      <code type="none">
-   {version,"1.2"}.
-   [{config_func,{Module,Function,Arguments}}].      </code>
-      <p><c>Module</c> is the name of the module where the callback
-        function is defined. <c>Function</c> is the name of the
-        callback function, and <c>Arguments</c> is the list of
-        arguments to the callback function.</p>
-    </section>
-
-    <section>
-      <title>The configuration function</title>
-      <p>The *.tool file points out a configuration function. This
-        function must return a list of configuration parameters (see
-        the Reference Manual for <seealso marker="webtool">webtool</seealso>).</p>
-      <p>The <c>web_data</c> parameter is mandatory and it specifies
-        the name of the tool and the link to the tool's start
-        page. All other parameters are optional.</p>
-      <p>If the tool requires any processes to run, the <c>start</c>
-        parameter specifies the function that WebTool must call in
-        order to start the process(es).</p>
-      <p>The <c>alias</c> parameters are passed directly on to the
-        webserver (INETS). The webserver has three ways to create
-        dynamic web pages CGI, Eval Scheme and Erl Scheme. All tools
-        running under WebTool must use Erl Scheme.</p>
-      <p>Erl Scheme tries to resemble plain CGI. The big difference is
-        that Erl Scheme can only execute Erlang code. The code will
-        furthermore be executed on the same instance as the webserver.</p>
-      <p>An URL which calls an Erlang function with Erl Scheme can have
-        the following syntax:</p>
-      <code type="none"><![CDATA[
-http://Servername:Port/ErlScriptAlias/Mod/Func<?QueryString>      ]]></code>
-      <p>An <c>alias</c> parameter in the configuration function can be
-        an ErlScriptAlias as used in the above URL. The definition of
-        an ErlScriptAlias shall be like this:</p>
-      <p><c>{alias,{erl_alias,Path,[Modules]}}</c>, e.g.</p>
-      <p><c>{alias,{erl_alias,"/testtool",[helloworld]}}</c></p>
-      <p>The following URL will then cause a call to the function
-        helloworld:helloworld/2 (if WebTool is started with default
-        settings i.e. servername "localhost" and port 8888):</p>
-      <p><c>http://localhost:8888/testtool/helloworld/helloworld</c></p>
-      <p>Note that the module <c>helloworld</c> must be in the code
-        path of the node running WebTool.</p>
-      <p>Functions that are called via the Erl Scheme must take two 
-        arguments, <c>Environment</c> and <c>Input</c>. 
-        </p>
-      <list type="bulleted">
-        <item><c>Environment</c> is a list of key/value tuples.</item>
-        <item><c>Input</c> is the part of the URL after the "?", i.e. the
-         part of the URL containing name-value pairs. If the page was
-         called with the URL:
-                <br></br>
-<c><![CDATA[http://localhost:8888/testtool/helloworld/helloworld?input1=one&amp;input2=two]]></c>        <br></br>
-<c>Input</c> will be the string
-        <c><![CDATA["input1=one&amp;input2=two"]]></c>.  In the module
-        <c>httpd</c> in the INETS application there is a function
-        <c>parse_query</c> which will parse such a string and return
-         a list of key-value tuples.</item>
-      </list>
-      <p>An <c>alias</c> parameter in the configuration function can
-        also be a normal path alias. This can e.g. be used to point
-        out a directory where HTML files are stored. The following
-        definition states that the URL
-        <c>http://localhost:8888/mytool_home/</c> really points to the
-        directory <c>/usr/local/otp/lib/myapp-1.0/priv</c>:</p>
-      <p><c>{alias,{"/mytool_home","/usr/local/otp/lib/myapp-1.0/priv"}}</c></p>
-      <p>See the INETS documentation, especially the module
-        <c>mod_esi</c>, for a more in depth coverage of the Erl Scheme.</p>
-    </section>
-
-    <section>
-      <title>A small example</title>
-      <p>A Hello World example that uses Erl Scheme would look like
-        this. Note that this example does not have a process running
-        and thus does not need a <c>start</c> parameter in the
-        configuration function.
-        </p>
-      <p><em>helloworld.erl:</em></p>
-      <pre>
-        -module(helloworld).
-        -export([config_data/0]).
-        -export([helloworld/2]).
-        
-        config_data()->
-            {testtool,
-             [{web_data,{"TestTool","/testtool/helloworld/helloworld"}},
-              {alias,{erl_alias,"/testtool",[helloworld]}}]}.
-        
-        helloworld(_Env,_Input)-&gt;
-            [header(),html_header(),helloworld_body(),html_end()].
-
-        header() -&gt;
-            header("text/html").
-
-        header(MimeType) -&gt;
-            "Content-type: " ++ MimeType ++ "\r\n\r\n".
-
-        html_header() -&gt;    
-            "&lt;HTML&gt;
-               &lt;HEAD&gt;
-                  &lt;TITLE&gt;Hello world Example &lt;/TITLE&gt;
-               &lt;/HEAD&gt;\n".
-
-        helloworld_body()-&gt;
-            "&lt;BODY&gt;Hello World&lt;/BODY&gt;".
-
-        html_end()-&gt;
-            "&lt;/HTML&gt;".
-      </pre>
-      <p>To use this example with WebTool a *.tool file must be created
-        and added to a directory in the current path, e.g. the same
-        directory as the compiled <c>helloworld.beam</c>.</p>
-      <p><em>testtool.tool:</em></p>
-      <code type="none">
-        {version,"1.2"}.
-        [{config_func, {helloworld,config_data,[]}}].
-      </code>
-      <p>When <c>helloworld.erl</c> is compiled, start WebTool by
-        calling the function <c>webtool:start()</c> and point your
-        browser to <em>http://localhost:8888/</em>. Select WebTool in
-        the topmost frame and start TestTool from the web page.  Click
-        on the link labeled <em>TestTool</em> in the topmost frame.</p>

-#   target system must have a working `dlsym(RTLD_NEXT, <S>)' implementation
-#   that can be used on `brk' and `sbrk' symbols used by the `malloc()'
-#   implementation in use, and by this track the `malloc()' implementations
-#   core memory usage. This is currently only used by unsupported features.
