     <p>In OTP, <em>application</em> denotes a component implementing

       directory <c>$OTPROOT/lib</c>, where <c>$OTPROOT</c> is
       the installation directory of Erlang/OTP, <c>code:root_dir()</c>.
       Directories can be named <c>Name[-Vsn]</c> and the code server,
       by default, chooses the directory with the highest version number
-      among those which have the same <c>Name</c>. The <c>-Vsn</c>
-      suffix is optional. If an <c>ebin</c> directory exists under
-      <c>Name[-Vsn]</c>, it is this directory which is added to
-      the code path.</p>
-    <p>The environment variable <c>ERL_LIBS</c> (defined in the operating
-      system) can be used to define additional library directories that
-      will be handled in the same way as the standard OTP library

-    <title>Code Path Cache</title>

-      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>
+      <p><em>Example:</em></p>
+    <p>On a Unix-like system, <c>ERL_LIBS</c> can be set to the following</p>

   <description>
-    <p><c>disk_log</c> is a disk based term logger which makes
-      it possible to efficiently log items on files. 
-      Two types of logs are supported,
-      <em>halt logs</em> and <em>wrap logs</em>. A halt log
-      appends items to a single file, the size of which may or may
-      not be limited by the disk log module, whereas a wrap log utilizes
-      a sequence of wrap log files of limited size. As a wrap log file
-      has been filled up, further items are logged onto to the next 
-      file in the sequence, starting all over with the first file when 
-      the last file has been filled up. For the sake of efficiency, 
-      items are always written to files as binaries.
-      </p>
-    <p>Two formats of the log files are supported, the <em>internal format</em> and the <em>external format</em>. The internal
-      format supports automatic repair of log files that have not been
-      properly closed, and makes it possible to efficiently read
-      logged items in <em>chunks</em> using a set of functions defined
-      in this module. In fact, this is the only way to read internally
-      formatted logs. The external format leaves it up to the user to
-      read the logged deep byte lists. The disk log module cannot
-      repair externally formatted logs. An item logged to an
-      internally formatted log must not occupy more than 4 GB of disk
-      space (the size must fit in 4 bytes).

-      A process that opens a disk log can either be an <em>owner</em> 
+      A process that opens a disk log can be an <em>owner</em>
       or an anonymous <em>user</em> of the disk log. Each owner is 
-      linked to the disk log 
-      process, and the disk log is closed by the owner should the 
-      owner terminate. Owners can subscribe to <em>notifications</em>, 
-      messages of the form <c>{disk_log, Node, Log, Info}</c> that are sent
+      linked to the disk log process, and an owner can close the disk log
+      either explicitly (by calling <c>close/1</c> or <c>lclose/1,2</c>)
+      or by terminating.</p>
+      <p>Owners can subscribe to <em>notifications</em>,
+      messages of the form <c>{disk_log, Node, Log, Info}</c>, which are sent
       from the disk log process when certain events occur, see 
-      the commands below and in particular the <c>open/1</c> option 
-      <seealso marker="#notify">notify</seealso>. 
-      There can be several owners of a log, but a process cannot own a 
-      log more than once. One and the same process may, however,
-      open the log 
-      as a user more than once. For a disk log process to properly close 
-      its file and terminate, it must be closed by its owners and once by 
-      some non-owner process for each time the log was used anonymously;
-      the users are counted, and there must not be any users left when the

         <p>Unloading can be described as the process of telling the
           emulator that this particular part of the code in this
-          particular process (i.e. this <seealso marker="#users">user</seealso>) no longer needs the
-          driver. That can, if there are no other users, trigger
-          actual unloading of the driver, in which case the driver
-          name disappears from the system and (if possible) the memory
-          occupied by the driver executable code is reclaimed. If the
-          driver has the <c>kill_ports</c> option set, or if
-          <c>kill_ports</c> was specified as an option to this
-          function, all pending ports using this driver will get
-          killed when unloading is done by the last <seealso marker="#users">user</seealso>. If no port-killing is
-          involved and there are open ports, the actual unloading
-          is delayed until there are no more open ports using the
-          driver. If, in this case, another <seealso marker="#users">user</seealso> (or even this user) loads the

-          unloading will never take place.</p>
-        <p>To allow the <seealso marker="#users">user</seealso> that
-          <em>requests unloading</em> to wait for <em>actual unloading</em> to
-          take place, <c>monitor</c> triggers can be specified in much
-          the same way as when loading. As <seealso marker="#users">users</seealso> of this function however
-          seldom are interested in more than decrementing the
-          reference counts, monitoring is more seldom needed. If the
-          <c>kill_ports</c> option is used however, monitor trigging is
-          crucial, as the ports are not guaranteed to have been killed
-          until the driver is unloaded, why a monitor should be
-          triggered for at least the <c>pending_driver</c> case.</p>

     <p>The Erlang <em>error logger</em> is an event manager (see

+      registered as <c>error_logger</c>. Errors, warnings, and info events
       are sent to the error logger from the Erlang runtime system and
       the different Erlang/OTP applications. The events are, by default,
-      logged to tty. Note that an event from a process <c>P</c> is
+      logged to the terminal. Notice that an event from a process <c>P</c> is
       logged at the node of the group leader of <c>P</c>. This means
       that log output is directed to the node from which a process was
       created, which not necessarily is the same node as where it is
       executing.</p>

+    <p>Initially, <c>error_logger</c> has only a primitive event
       handler, which buffers and prints the raw event messages. During
-      system startup, the application Kernel replaces this with a
-      <em>standard event handler</em>, by default one which writes
-      nicely formatted output to tty. Kernel can also be configured so
-      that events are logged to file instead, or not logged at all, see

+      configured so that events are logged to a file instead, or not logged at all,
+      see <seealso marker="kernel_app"><c>kernel(6)</c></seealso>.</p>
     <p>Also the SASL application, if started, adds its own event
-      handler, which by default writes supervisor, crash and progress
-      reports to tty. See
-      <seealso marker="sasl:sasl_app">sasl(6)</seealso>.</p>
-    <p>It is recommended that user defined applications should report
-      errors through the error logger, in order to get uniform reports.
-      User defined event handlers can be added to handle application
-      specific events. (<c>add_report_handler/1,2</c>). Also, there is
-      a useful event handler in STDLIB for multi-file logging of events,
-      see <c>log_mf_h(3)</c>.</p>
-    <p>Warning events was introduced in Erlang/OTP R9C. To retain
-      backwards compatibility, these are by default tagged as errors,
-      thus showing up as error reports in the logs. By using
-      the command line flag <c><![CDATA[+W <w | i>]]></c>, they can instead
-      be tagged as warnings or info. Tagging them as warnings may
-      require rewriting existing user defined event handlers.</p>

+    <p>On operating systems with thread support,
+      file operations can be performed in threads of their own, allowing

-      the file operations. See the command line flag

-    <p>The Erlang VM supports file names in Unicode to a limited
-    extent.  Depending on how the VM is started (with the parameter
-    <c>+fnu</c> or <c>+fnl</c>), file names given can contain
-    characters > 255 and the VM system will convert file names
-    back and forth to the native file name encoding.</p>
+    <p>Regarding filename encoding, the Erlang VM can operate in
+    two modes. The current mode can be queried using function
+    <seealso marker="#native_name_encoding"><c>native_name_encoding/0</c></seealso>.
+    It returns <c>latin1</c> or <c>utf8</c>.</p>
 
-    <p>The default behavior for Unicode character translation depends
-    on to what extent the underlying OS/filesystem enforces consistent
-    naming. On OSes where all file names are ensured to be in one or
-    another encoding, Unicode is the default (currently this holds for
-    Windows and MacOSX). On OSes with completely transparent file
-    naming (i.e. all Unixes except MacOSX), ISO-latin-1 file naming is
-    the default. The reason for the ISO-latin-1 default is that
-    file names are not guaranteed to be possible to interpret according to
-    the Unicode encoding expected (i.e. UTF-8), and file names that
-    cannot be decoded will only be accessible by using &quot;raw
-    file names&quot;, in other word file names given as binaries.</p>
- 
-    <p>As file names are traditionally not binaries in Erlang,
-    applications that need to handle raw file names need to be
-    converted, why the Unicode mode for file names is not default on
-    systems having completely transparent file naming.</p>
+    <p>In <c>latin1</c> mode, the Erlang VM does not change the
+    encoding of filenames. In <c>utf8</c> mode, filenames can
+    contain Unicode characters greater than 255 and the VM
+    converts filenames back and forth to the native filename encoding
+    (usually UTF-8, but UTF-16 on Windows).</p>
 
-    <note>
-      <p>As of R14B01, the most basic file handling modules
-      (<c>file</c>, <c>prim_file</c>, <c>filelib</c> and
-      <c>filename</c>) accept raw file names, but the rest of OTP is not
-      guaranteed to handle them, why Unicode file naming on systems
-      where it is not default is still considered experimental.</p>
-    </note>
+    <p>The default mode depends on the operating system. Windows and
+    MacOS X enforce consistent filename encoding and therefore the
+    VM uses <c>utf8</c> mode.</p>
+
+    <p>On operating systems with transparent naming (for example, all Unix
+    systems except MacOS X), default is <c>utf8</c> if the
+    terminal supports UTF-8, otherwise <c>latin1</c>. The default can
+    be overridden using <c>+fnl</c> (to force <c>latin1</c> mode)
+    or <c>+fnu</c> (to force <c>utf8</c> mode) when starting
+    <seealso marker="erts:erl"><c>erts:erl</c></seealso>.</p>
 
-    <p>Raw file names is a new feature in OTP R14B01, which allows the
-    user to supply completely uninterpreted file names to the
-    underlying OS/filesystem. They are supplied as binaries, where it
-    is up to the user to supply a correct encoding for the
-    environment. The function <c>file:native_name_encoding()</c> can
-    be used to check what encoding the VM is working in. If the
-    function returns <c>latin1</c> file names are not in any way
-    converted to Unicode, if it is <c>utf8</c>, raw file names should
-    be encoded as UTF-8 if they are to follow the convention of the VM
-    (and usually the convention of the OS as well). Using raw
-    file names is useful if you have a filesystem with inconsistent
-    file naming, where some files are named in UTF-8 encoding while
-    others are not. A file:list_dir on such mixed file name systems
-    when the VM is in Unicode file name mode might return file names as
-    raw binaries as they cannot be interpreted as Unicode
-    file names. Raw file names can also be used to give UTF-8 encoded
-    file names even though the VM is not started in Unicode file name
-    translation mode.</p>
+    <p>On operating systems with transparent naming, files can be
+    inconsistently named, for example, some files are encoded in UTF-8 while
+    others are encoded in ISO Latin-1. The concept of <em>raw filenames</em> is
+    introduced to handle file systems with inconsistent naming when running in
+    <c>utf8</c> mode.</p>
+
+    <p>A <em>raw filename</em> is a filename specified as a binary. The Erlang VM
+    does not translate a filename specified as a binary on
+    systems with transparent naming.</p>
+
+    <p>When running in <c>utf8</c> mode, functions
+    <seealso marker="#list_dir/1"><c>list_dir/1</c></seealso> and
+    <seealso marker="#read_link/1"><c>read_link/1</c></seealso>
+    never return raw filenames. To return all filenames including raw filenames,
+    use functions
+    <seealso marker="#list_dir_all"><c>list_dir_all/1</c></seealso> and
+    <seealso marker="#read_link_all"><c>read_link_all/1</c></seealso>.</p>

+    <p>See also section <seealso marker="stdlib:unicode_usage#notes-about-raw-filenames">Notes About Raw Filenames</seealso> in the STDLIB User's Guide.</p>
 
-    <p>Note that on Windows, <c>file:native_name_encoding()</c>
-    returns <c>utf8</c> per default, which is the format for raw
-    file names even on Windows, although the underlying OS specific
-    code works in a limited version of little endian UTF16. As far as
-    the Erlang programmer is concerned, Windows native Unicode format
-    is UTF-8...</p>

-        <p>Applications that access databases or log files often write

-          time stored in the inode. If the modification time is not a part

     <p>The registered names are stored in replica global name tables on

       the translation of a name to a pid is fast, as it is always done

     <p>The global name server also performs the critical task of

-    <p>In the situation where a node has lost its connections to other

-      global groups, a request from another global group may produce an

     <p>This modules contains the interface to the <c>heart</c> process.

       it is supervising is still running. If the port program has not
       received any heartbeats within <c>HEART_BEAT_TIMEOUT</c> seconds
-      (default is 60 seconds), the system can be rebooted. Also, if
-      the system is equipped with a hardware watchdog timer and is
-      running Solaris, the watchdog can be used to supervise the entire
-      system.</p>
-    <p>An Erlang runtime system to be monitored by a heart program,
-      should be started with the command line flag <c>-heart</c> (see

+    <p>To reboot on Windows, <c>HEART_COMMAND</c> can be

-      or of course to any other suitable program which can activate a
-      reboot.</p>
-    <p>The hardware watchdog will not be started under Solaris if

-    <p>The <c>HEART_BEAT_TIMEOUT</c> and <c>HEART_BEAT_BOOT_DELAY</c>

+    <p>The environment variable <c>HEART_BEAT_TIMEOUT</c>

-    <p>It should be noted that if the system clock is adjusted with

-              behaviour. To make programming easier, a socket where
-              the peer closed and this was detected while in

-              <c>{tcp_closed,Socket}</c> when set to <c>{active, once}</c> or <c>{active, true}</c> mode. It is therefore

-              <c>{tcp_closed,Socket}</c>, possibly followed by socket
-              port termination (depending on the <c>exit_on_close</c>
-              option) will eventually appear when a socket changes

+              the peer closed, and this is detected while in
+              <c>{active, false}</c> mode, still generates message
+              <c>{tcp_closed,Socket}</c> when set to <c>{active, once}</c>,

-              <em>when</em> peer closing is detected is all up to the

-            <p>Note that <c>{active,true}</c> mode provides no flow

+	      before associating it to an address. It is therefore only
+	      reasonable to specify it when creating the socket and not
+	      to use it when calling function
+	      (<seealso marker="#setopts/2"><c>setopts/2</c></seealso>)
+	      containing this description.</p>
+	    <p>The behavior of a socket with this option set to
+	      <c>true</c> is the only portable one. The original
+	      idea when IPv6 was new of using IPv6 for all traffic
+	      is now not recommended by FreeBSD (you can use
+	      <c>{ipv6_v6only,false}</c> to override the recommended
+	      system default value),
+	      forbidden by OpenBSD (the supported GENERIC kernel),
+	      and impossible on Windows (which has separate
+	      IPv4 and IPv6 protocol stacks). Most Linux distros
+	      still have a system default value of <c>false</c>.
+	      This policy shift among operating systems to
+	      separate IPv6 from IPv4 traffic has evolved, as
+	      it gradually proved hard and complicated to get
+	      a dual stack implementation correct and secure.</p>
+	    <p>On some platforms, the only allowed value for this option
+	      is <c>true</c>, for example, OpenBSD and Windows. Trying to set
+	      this option to <c>false</c>, when creating the socket, fails
+	      in this case.</p>
+	    <p>Setting this option on platforms where it does not exist
+	      is ignored. Getting this option with
+	      <seealso marker="#getopts/2"><c>getopts/2</c></seealso>
+	      returns no value, that is, the returned list does not contain an
+	      <c>{ipv6_v6only,_}</c> tuple. On Windows, the option
+	      does not exist, but it is emulated as a
+	      read-only option with value <c>true</c>.</p>
+	    <p>Therefore, setting this option to <c>true</c>
+	      when creating a socket never fails, except possibly on a
+              platform where you
+	      have customized the kernel to only allow <c>false</c>,
+	      which can be doable (but awkward) on, for example, OpenBSD.</p>
+	    <p>If you read back the option value using
+	      <seealso marker="#getopts/2"><c>getopts/2</c></seealso>
+	      and get no value, the option does not exist in the host
+              operating system. The behavior of both an IPv6 and an IPv4
+	      socket listening on the same port, and for an IPv6 socket
+	      getting IPv4 traffic is then no longer predictable.</p>

+	    Add the {active,N} socket option for TCP, UDP, and SCTP,
+	    where N is an integer in the range -32768..32767, to
+	    allow a caller to specify the number of data messages to
+	    be delivered to the controlling process. Once the
+	    socket's delivered message count either reaches 0 or is
+	    explicitly set to 0 with inet:setopts/2 or by including
+	    {active,0} as an option when the socket is created, the
+	    socket transitions to passive ({active, false}) mode and
+	    the socket's controlling process receives a message to
+	    inform it of the transition. TCP sockets receive
+	    {tcp_passive,Socket}, UDP sockets receive
+	    {udp_passive,Socket} and SCTP sockets receive
+	    {sctp_passive,Socket}. </p>
+          <p>
+	    The socket's delivered message counter defaults to 0, but
+	    it can be set using {active,N} via any gen_tcp, gen_udp,
+	    or gen_sctp function that takes socket options as
+	    arguments, or via inet:setopts/2. New N values are added
+	    to the socket's current counter value, and negative
+	    numbers can be used to reduce the counter value.
+	    Specifying a number that would cause the socket's counter
+	    value to go above 32767 causes an einval error. If a
+	    negative number is specified such that the counter value
+	    would become negative, the socket's counter value is set
+	    to 0 and the socket transitions to passive mode. If the
+	    counter value is already 0 and inet:setopts(Socket,
+	    [{active,0}]) is specified, the counter value remains at
+	    0 but the appropriate passive mode transition message is
+	    generated for the socket.</p>

+	    A call to either the <c>garbage_collect/1</c> BIF or the
+	    <c>check_process_code/2</c> BIF may trigger garbage
+	    collection of another processes than the process calling
+	    the BIF. The previous implementations performed these
+	    kinds of garbage collections without considering the
+	    internal state of the process being garbage collected. In
+	    order to be able to more easily and more efficiently
+	    implement yielding native code, these types of garbage
+	    collections have been rewritten. A garbage collection
+	    like this is now triggered by an asynchronous request
+	    signal, the actual garbage collection is performed by the
+	    process being garbage collected itself, and finalized by
+	    a reply signal to the process issuing the request. Using
+	    this approach processes can disable garbage collection
+	    and yield without having to set up the heap in a state

+	    A bug in prim_inet has been corrected. If the port owner
+	    was killed at a bad time while closing the socket port
+	    the port could become orphaned hence causing port and
+	    socket leaking. Reported by Fred Herbert, Dmitry Belyaev
+	    and others.</p>

-  <description>
-    <warning><p>
-      Packages has since it was introduced more than 5 years ago been an 
-      experimental feature. Use it at your own risk, we do not
-      actively maintain and develop this feature. It might however be 
-      supported some 
-      day.
-      </p>
-      <p>
-	In spite of this packages work quite well, but there are some 
-	known issues in tools and other parts where packages don't work well.
-    </p>
-    </warning>
-    <p><em>Introduction</em></p>
-    <p>Packages are simply namespaces for modules. 
-      All old Erlang modules automatically belong to the top level 
-      ("empty-string") namespace, and do not need any changes.</p>
-    <p>The full name of a packaged module is written as e.g. 
-      "<c>fee.fie.foe.foo</c>",
-      i.e., as atoms separated by periods, 
-      where the package name is the part up to
-      but not including the last period; 
-      in this case "<c>fee.fie.foe</c>".
-      A more concrete example is the module <c>erl.lang.term</c>, 
-      which is in the
-      package <c>erl.lang</c>. 
-      Package names can have any number of segments, as in 
-      <c>erl.lang.list.sort</c>.
-      The atoms in the name can be quoted, as in <c>foo.'Bar'.baz</c>, 
-      or even the
-      whole name, as in <c>'foo.bar.baz'</c> but the concatenation of 
-      atoms and
-      periods must not contain two consecutive period characters or 
-      end with a period,
-      as in <c>'foo..bar'</c>, <c>foo.'.bar'</c>, or <c>foo.'bar.'</c>. 
-      The periods must not be followed by whitespace.</p>
-    <p>The code loader maps module names onto the file system directory 
-      structure.
-      E.g., the module <c>erl.lang.term</c> corresponds to a file 
-      <c>.../erl/lang/term.beam</c>
-      in the search path. 
-      Note that the name of the actual object file corresponds to
-      the last part only of the full module name. 
-      (Thus, old existing modules such as <c>lists</c>
-      simply map to <c>.../lists.beam</c>, exactly as before.)</p>
-    <p>A packaged module in a file "<c>foo/bar/fred.erl</c>" is declared
-      as:</p>
-    <code type="none">
--module(foo.bar.fred).</code>
-    <p>This can be compiled and loaded from the Erlang shell using 
-      <c>c(fred)</c>, if
-      your current directory is the same as that of the file. 
-      The object file will be named <c>fred.beam</c>.</p>
-    <p>The Erlang search path works exactly as before, 
-      except that the package segments will be appended to each 
-      directory in the path in order to find the
-      file. E.g., assume the path is <c>["/usr/lib/erl", "/usr/local/lib/otp/legacy/ebin", "/home/barney/erl"]</c>.
-      Then, the code for a module named <c>foo.bar.fred</c> will be 
-      searched for
-      first as <c>"/usr/lib/erl/foo/bar/fred.beam"</c>, then 
-      <c>"/usr/local/lib/otp/legacy/ebin/foo/bar/fred.beam"</c>
-      and lastly <c>"/home/barney/erl/foo/bar/fred.beam"</c>. 
-      A module
-      like <c>lists</c>, which is in the top-level package, 
-      will be looked for as <c>"/usr/lib/erl/lists.beam"</c>,
-      <c>"/usr/local/lib/otp/legacy/ebin/lists.beam"</c> and 
-      <c>"/home/barney/erl/lists.beam"</c>.</p>
-    <p><em>Programming</em></p>
-    <p>Normally, if a call is made from one module to another, 
-      it is assumed that the
-      called module belongs to the same package as the source module. 
-      The compiler
-      automatically expands such calls. E.g., in:</p>
-    <code type="none">
--module(foo.bar.m1).
--export([f/1]).
-
-f(X) -> m2:g(X).</code>
-    <p><c>m2:g(X)</c> becomes a call to <c>foo.bar.m2</c>
-      If this is not what was intended, the call can be written 
-      explicitly, as in</p>
-    <code type="none">
--module(foo.bar.m1).
--export([f/1]).
-
-f(X) -> fee.fie.foe.m2:g(X).</code>
-    <p>Because the called module is given with an explicit package name, 
-      no expansion is done in this case.</p>
-    <p>If a module from another package is used repeatedly in a module, 
-      an import declaration can make life easier:</p>
-    <code type="none">
--module(foo.bar.m1).
--export([f/1, g/1]).
--import(fee.fie.foe.m2).
-
-f(X) -> m2:g(X).
-g(X) -> m2:h(X).</code>
-    <p>will make the calls to <c>m2</c> refer to <c>fee.fie.foe.m2</c>. 
-      More generally, a declaration <c>-import(Package.Module).</c> 
-      will cause calls to <c>Module</c>
-      to be expanded to <c>Package.Module</c>.</p>
-    <p>Old-style function imports work as normal (but full module 
-      names must be
-      used); e.g.:</p>
-    <code type="none">
--import(fee.fie.foe.m2, [g/1, h/1]).</code>
-    <p>however, it is probably better to avoid this form of import 
-      altogether in new
-      code, since it makes it hard to see what calls are really "remote".</p>
-    <p>If it is necessary to call a module in the top-level package 
-      from within a
-      named package, the module name can be written either with an 
-      initial period as
-      in e.g. "<c>.lists</c>", or with an empty initial atom, as in 
-      "<c>''.lists</c>".
-      However, the best way is to use an import declaration - 
-      this is most obvious to
-      the eye, and makes sure we don't forget adding a period somewhere:</p>
-    <code type="none">
--module(foo.bar.fred).
--export([f/1]).
--import(lists).
-
-f(X) -> lists:reverse(X).</code>
-    <p>The dot-syntax for module names can be used in any expression. 
-      All segments must
-      be constant atoms, and the result must be a well-formed 
-      package/module name.
-      E.g.:</p>
-    <code type="none">
-spawn(foo.bar.fred, f, [X])</code>
-    <p>is equivalent to <c>spawn('foo.bar.fred', f, [X])</c>.</p>
-    <p><em>The Erlang Shell</em></p>
-    <p>The shell also automatically expands remote calls, 
-      however currently no
-      expansions are made by default. 
-      The user can change the behaviour by using the <c>import/1</c>
-      shell command (or its abbreviation <c>use/1</c>). E.g.:</p>
-    <pre>
-1> <input>import(foo.bar.m).</input>
-ok
-2> <input>m:f().</input></pre>
-    <p>will evaluate <c>foo.bar.m:f()</c>. 
-      If a new import is made of the same name,
-      this overrides any previous import. 
-      (It is likely that in the future, some
-      system packages will be pre-imported.)</p>
-    <p>In addition, the shell command <c>import_all/1</c> 
-      (and its alias <c>use_all/1</c>)
-      imports all modules currently found in the path for a given 
-      package name. E.g.,
-      assuming the files "<c>.../foo/bar/fred.beam</c>", 
-      "<c>.../foo/bar/barney.beam</c>"
-      and "<c>.../foo/bar/bambam.beam</c>" can be found from our current
-      path,</p>
-    <pre>
-1> <input>import_all(foo.bar).</input></pre>
-    <p>will make <c>fred</c>, <c>barney</c> and <c>bambam</c> 
-      expand to <c>foo.bar.fred</c>,
-      <c>foo.bar.barney</c> and <c>foo.bar.bambam</c>, respectively.</p>
-    <p>Note: The compiler does not have an "import all" directive, for the
-      reason that Erlang has no compile time type checking. 
-      E.g. if the wrong search
-      path is used at compile time, a call <c>m:f(...)</c> 
-      could be expanded to <c>foo.bar.m:f(...)</c>
-      without any warning, instead of the intended 
-      <c>frob.ozz.m:f(...)</c>, if
-      package <c>foo.bar</c> happens to be found first in the path. 
-      Explicitly
-      declaring each use of a module makes for safe code.</p>

-HOW THE DISTRIBUTION HANDSHAKE WORKS
-------------------------------------
-
-This document describes the distribution handshake introduced in 
-the R6 release of Erlang/OTP.
-
-GENERAL
--------
-
-The TCP/IP distribution uses a handshake which expects a
-connection based protocol, i.e. the protocol does not include
-any authentication after the handshake procedure.
-
-This is not entirely safe, as it is vulnerable against takeover
-attacks, but it is a tradeoff between fair safety and performance.
-
-The cookies are never sent in cleartext and the handshake procedure
-expects the client (called A) to be the first one to prove that it can 
-generate a sufficient digest. The digest is generated with the 
-MD5 message digest algorithm and the challenges are expected to be very
-random numbers.
-
-DEFINITIONS
------------
-
-A challenge is a 32 bit integer number in big endian order. Below the function
-gen_challenge() returns a random 32 bit integer used as a challenge.
-
-A digest is a (16 bytes) MD5 hash of [the Challenge (as text) concatenated
-with the cookie (as text)]. Below, the function gen_digest(Challenge, Cookie)
-generates a digest as described above.
-
-An out_cookie is the cookie used in outgoing communication to a certain node,
-so that A's out_cookie for B should correspond with B's in_cookie for A and 
-the other way around. A's out_cookie for B and A's in_cookie for B need *NOT*
-be the same. Below the function out_cookie(Node) returns the current
-node's out_cookie for Node.
-
-An in_cookie is the cookie expected to be used by another node when 
-communicating with us, so that A's in_cookie for B corresponds with B's 
-out_cookie for A. Below the function in_cookie(Node) returns the current
-node's in_cookie for Node.
-
-The cookies are text strings that can be viewed as passwords.
-
-Every message in the handshake starts with a 16 bit big endian integer 
-which contains the length of the message (not counting the two initial bytes).
-In erlang this corresponds to the gen_tcp option {packet, 2}. Note that after 
-the handshake, the distribution switches to 4 byte packet headers.
-
-THE HANDSHAKE IN DETAIL
------------------------
- 
-Imagine two nodes, node A, which initiates the handshake and node B, which
-accepts the connection.
-
-1) connect/accept: A connects to B via TCP/IP and B accepts the connection.
-
-2) send_name/receive_name: A sends an initial identification to B. 
-B receives the message. The message looks
-like this (every "square" being one byte and the packet header removed):
-
-+---+--------+--------+-----+-----+-----+-----+-----+-----+-...-+-----+
-|'n'|Version0|Version1|Flag0|Flag1|Flag2|Flag3|Name0|Name1| ... |NameN|
-+---+--------+--------+-----+-----+-----+-----+-----+-----+-... +-----+
-
-The 'n' is just a message tag,
-Version0 & Version1 is the distribution version selected by node A,
-                    based on information from EPMD. (16 bit big endian)
-Flag0 ... Flag3 are capability flags, the capabilities defined in dist.hrl.
-                (32 bit big endian)
-Name0 ... NameN is the full nodename of A, as a string of bytes (the
-                packet length denotes how long it is).
-
-3) recv_status/send_status: B sends a status message to A, which indicates
-if the connection is allowed. Four different status codes are defined:
-ok: The handshake will continue.
-ok_simultaneous: The handshake will continue, but A is informed that B
-                 has another ongoing connection attempt that will be
-		 shut down (simultaneous connect where A's name is 
-		 greater than B's name, compared literally),
-nok: The handshake will not continue, as B already has an ongoing handshake
-     which it itself has initiated. (simultaneous connect where B's name is 
-     greater than A's)
-not_allowed: The connection is disallowed for some (unspecified) security 
-             reason.
-alive: A connection to the node is already active, which either means
-       that node A is confused or that the TCP connection breakdown
-       of a previous node with this name has not yet reached node B.
-       See 3B below.
-
-This is the format of the status message:
-
-+---+-------+-------+-...-+-------+
-|'s'|Status0|Status1| ... |StatusN|
-+---+-------+-------+-...-+-------+
-
-'s' is the message tag
-Status0 ... StatusN is the status as a string (not terminated)
-
-3B) send_status/recv_status: If status was 'alive', node A will answer with
-another status message containing either 'true' which means that the
-connection should continue (The old connection from this node is broken), or
-'false', which simply means that the connection should be closed, the 
-connection attempt was a mistake.
-
-4) recv_challenge/send_challenge: If the status was 'ok' or 'ok_simultaneous',
-The handshake continues with B sending A another message, the challenge.
-The challenge contains the same type of information as the "name" message 
-initially sent from A to B, with the addition of a 32 bit challenge:
-
-+---+--------+--------+-----+-----+-----+-----+-----+-----+-----+-----+---
-|'n'|Version0|Version1|Flag0|Flag1|Flag2|Flag3|Chal0|Chal1|Chal2|Chal3|
-+---+--------+--------+-----+-----+-----+-----+-----+-----+-----+-----+---
-   ------+-----+-...-+-----+
-    Name0|Name1| ... |NameN|
-   ------+-----+-... +-----+
-
-Where Chal0 ... Chal3 is the challenge as a 32 bit big endian integer
-and the other fields are B's version, flags and full nodename.
-
-5) send_challenge_reply/recv_challenge_reply: Now A has generated
-a digest and its own challenge. Those are sent together in a package
-to B:
-
-+---+-----+-----+-----+-----+-----+-----+-----+-----+-...-+------+
-|'r'|Chal0|Chal1|Chal2|Chal3|Dige0|Dige1|Dige2|Dige3| ... |Dige15|
-+---+-----+-----+-----+-----+-----+-----+-----+-----+-...-+------+
-
-Where 'r' is the tag, Chal0 ... Chal3 is A's challenge for B to handle and
-Dige0 ... Dige15 is the digest that A constructed from the challenge B sent

-6) recv_challenge_ack/send_challenge_ack: B checks that the digest received
-from A is correct and generates a digest from the challenge received from 
-A. The digest is then sent to A. The message looks like this:
-
-+---+-----+-----+-----+-----+-...-+------+
-|'a'|Dige0|Dige1|Dige2|Dige3| ... |Dige15|
-+---+-----+-----+-----+-----+-...-+------+
-
-Where 'a' is the tag and Dige0 ... Dige15 is the digest calculated by B
-for A's challenge.
-
-7) A checks the digest from B and the connection is up.

-THE CURRENTLY DEFINED FLAGS
----------------------------
-Currently the following capability flags are defined:
-
-%% The node should be published and part of the global namespace
--define(DFLAG_PUBLISHED,1).
-
-%% The node implements an atom cache
--define(DFLAG_ATOM_CACHE,2).
-
-%% The node implements extended (3 * 32 bits) references
--define(DFLAG_EXTENDED_REFERENCES,4).
-
-%% The node implements distributed process monitoring.
--define(DFLAG_DIST_MONITOR,8).
- 
-%% The node uses separate tag for fun's (lambdas) in the distribution protocol.
--define(DFLAG_FUN_TAGS,16).
- 
-An R6 erlang node implements all of the above, while a C or Java node only
-implements DFLAG_EXTENDED_REFERENCES.
