-    <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>
