+# This will read a 'c' file and scan for embedded comments in the
+# style of gnome comments (+minor extensions - see below).
+#
+
+# Note: This only supports 'c'.
+
+# usage:
+# kerneldoc [ -docbook | -html | -text | -man ]
+# [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
+# or
+# [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
+#
+# Set output format using one of -docbook -html -text or -man. Default is man.
+#
+# -function funcname
+# If set, then only generate documentation for the given function(s). All
+# other functions are ignored.
+#
+# -nofunction funcname
+# If set, then only generate documentation for the other function(s). All
+# other functions are ignored. Cannot be used with -function together
+# (yes thats a bug - perl hackers can fix it 8))
+#
+# c files - list of 'c' files to process
+#
+# All output goes to stdout, with errors to stderr.
+
+#
+# format of comments.
+# In the following table, (...)? signifies optional structure.
+# (...)* signifies 0 or more structure elements
+# /**
+# * function_name(:)? (- short description)?
+# (* @parameterx: (description of parameter x)?)*
+# (* a blank line)?
+# * (Description:)? (Description of function)?
+# * (section header: (section description)? )*
+# (*)?*/
+#
+# So .. the trivial example would be:
+#
+# /**
+# * my_function
+# **/
+#
+# If the Description: header tag is ommitted, then there must be a blank line
+# after the last parameter specification.
+# e.g.
+# /**
+# * my_function - does my stuff
+# * @my_arg: its mine damnit
+# *
+# * Does my stuff explained.
+# */
+#
+# or, could also use:
+# /**
+# * my_function - does my stuff
+# * @my_arg: its mine damnit
+# * Description: Does my stuff explained.
+# */
+# etc.
+#
+# All descriptions can be multiline, apart from the short function description.
+#

+# patterns, which are highlighted appropriately.

+ <title>Introduction</title>
+ <para>
+ This is some sample documentation for you project. You'll need to be
+ familiar with <ulink url="http://docbook.org">DocBook</ulink>
+ to make best use of Enlightenment's documentation scheme.
+ </para>
+ <para>
+ See <link linkend="files" endterm="files.title"></link>
+ for an explanation of the documentation setup in you project.
+ </para>
+ <para>
+ <link linkend="comments" endterm="comments.title"></link> explains
+ the way you have to structure your comments so that they can be
+ extracted.
+ </para>
+ <para>
+ <link linkend="samples" endterm="samples.title"></link> contains a few
+ layout and markup examples to get you up to speed quickly.

+ </chapter>
+
+ <chapter id="files">
+ <title id="files.title">Documentation File Structure</title>
+ <para>
+ The entire documentation setup lives in the <filename>doc</filename>
+ directory. The file you need to edit is called <filename>manual.raw</filename>.
+ When you enter <command>make docs</command> in the toplevel directory,
+ it gets translated into a standard SGML file using a Perl script.
+ The script scans the file for any lines starting directly with the
+ string <command>!I<filename></command>. Here,
+ <filename>filename</filename> is the name of a code
+ file in which you have put extractable comments. The Perl script will
+ then analyze the file and generate SGML DocBook statements for those
+ comments right into the output file.
+ </para>
+ <para>
+ The resulting file of that step is called <filename>$PACKAGE-manual-$VERSION.sgml</filename>
+ where PACKAGE and VERSION are automatically set during the build process.
+ This sgml file can be postprocessed with any SGML processor to generate
+ for example HTML, TeX or PDF output.
+ </para>
+ <para>
+ Suppport for HTML generation is included already through the
+ <command>make html-docs</command> target. In order to be able to use
+ that, you'll need to have <command>jade</command> installed, and appropriate
+ DocBook stylesheets. If the <command>configure</command> script doesn't automatically find
+ you stylesheets (on a Debian system it should), you can specify them when
+ calling <command>configure</command> or <command>autogen.sh</command> using
+ the <command>--with-dbsheets=DIR</command> option.
+ </para>
+ <para>
+ If everything worked out fine, you'll get a tarball of the HTML version
+ of your documentation and the extracted version in the docs directory,
+ named similarly to the SGML file.
+ </para>
+
+ </chapter>
+
+ <chapter id="comments">
+ <title id="comments.title">Writing Extractable Comments</title>
+ <para>
+ I'll simply give an example of a commented function here:
+
+ <programlisting>
+
+/**
+ * efsd_wait_event - blocking wait for next Efsd event.
+ * @ec: The Efsd connection
+ * @ev: Pointer to an allocated EfsdEvent.
+ *
+ * Blocks until an efsd event arrives, then returns it by filling
+ * in the @ev structure. Returns -1 when there was an error,
+ * >= 0 otherwise.
+ */
+int efsd_wait_event(EfsdConnection *ec, EfsdEvent *ev);
+ </programlisting>
+ As you can see, it's not hard -- just use two asterisks
+ to signal the start of an extractable comment. In the first
+ line, begin with the function name and a one-liner description.
+ Then, put each parameter in the following lines. Add an empty
+ line, and then a more verbose description. That's basically
+ it, you can also markup items differently as follows:
+
+ <itemizedlist mark="opencircle">
+ <listitem>
+ <para><command>funcname()</command> for function names</para>
+ </listitem>
+ <listitem>
+ <para><command>$ENVVAR</command> for environment variables</para>
