/**
* Documentation system for removing documentation from source files.
* <p>
* The documentation will be created in the directory /doc/autodoc. Extra
* documentation should be placed into the other help directories and will
* be accessed via the help system. The html documentation will be placed
* into the /www/autodoc directory. The files in theses directories will
* be named with the '/'s replaced with '.'s. ie: /obj/handlers/room_handler.c
* would be in the file /doc/autodoc/obj.handlers.room_handler.c and
* /www/autodoc/obj.handlers.room_handler.c.html. An index of the methods
* and object names will be generated from the input files and linked into the
* help system. An alphabetical index will also be produced that is linked
* to the html stuff.
* <p>
* The first comment which follows the comment format below and occurs right
* before a function will be used as the documentation for that function. The
* comment must start with two '*'s to distinguish it from a normal comment.
* A special tag at the start of one of the first comments in the file will
* signify that it is a comment for the class.
* <p>
* Only comments before a real function declaration will be used, comments
* before a predeclaration will be ignored.
* <p>
* Any function which is not declared as private and does not have the @ignore
* tag in its description will be placed into the resulting documentation
* file. This will be done even if no comment was found.
* <p>
* In the text part of the comment the main section is a free form
* documentation, it is merely a description of the whole function. After
* this several tags can be added to the comment which allows other things
* to be documented. All the text after the tag is taken as part of that
* tags information. The main tag should never actually be used, it
* is implied as being the tag associated with the first section of
* comment.
* <p>
* HTML tags will be used in the comments to allow certain things to
* happen. The tags 'p', 'b', 'i', 'code', 'ul', 'ol', 'dl', 'dd', 'dt', 'pre'
* and 'li' will be supported.
* <p>
* The sequences '\\/', '\\\\' and '\<' will be processed by the comment
* handling code so that they do not get placed into the output code.
* <p>
* White space is ignored... Both html and roff format files will be
* created from the documentation maker.
* <p>
* The supported tags are:
* <dl>
* <dt>@param
* <dd>Specify the parameter and what it does. This should be one short
* sentence only. There needs to be one of these for every
* parameter, the first word of the sentence is the name of the
* parameter and the rest is the description. There should be no full
* stop on the end of the sentance.
* <dt>@member
* <dd>This is used with classes and defines the members of the class. The
* definition is the same as for the @param element above.
* <dt>@return
* <dd>Specify what the return value is. This should be one short
* sentence only. Theres should only be one of these in every
* function. There should be no full stop on the end of the sentence.
* <dt>@see
* <dd>Specify an object or function to see. The format must be one of:
* <ul>
* <li> object_name<br><i>@see /global/new_parse</i>
* <li> function_name()<br><i>@see frog()</i>
* <li> object_name->function_name()<br><i>@see /global/new_parse->add_command()</i>
* <li> efun::name()<br><i>@see efun::sort_array()</i>
* <li> help::name<br><i>@see help::effects</i>
* </ul>
* <dt>@ignore
* <dd>Do not document this function, the whole comment is ignored.
* <dt>@main
* <dd>The main documentation section.
* <dt>@classification
* <dd>Used in the effects files to classify the effect. So a tree
* of the classifications can be derived.
* <dt>@index
* <dd>Adds in a new index reference on this name. This should be one
* word only.
* <dt>@change
* <dd>Placed in the class documentation to reference a change list.
* First line after the tag is the date and the author and
* then follows a description of the change.
* <dt>@example
* <dd>If you wish to embed an example in the code.
* <dt>@started
* <dd>When the file was started.
* <dt>@author
* <dd>The author of the file.
* </dl>
*
* The output format will look something like the API documentation for
* java. If you have not seen this before, go to http://www.javasoft.com
* and look in the JDK and then the API section.
* <p>
* Comment format:
* <pre>
* /\**
* * <text>
* * ..
* * <text>
* *
* *\/
* </pre>
*
* ie: it starts with a /\** and ends with a *\/ on a line by themselves and
* every intervening line has a * at the start. By using a \\ you can
* make characters escaped. This means they are not processed by
* the internal system, so to make a end comment appear inside a
* the text you go : *\\/
*
* @example
* inherit "/std/object";
*
* /\**
* * This class is a nice shade of blue and allows all other shades of
* * green and yellow to mix well.
* * @see yellow
* * @see blue
* * @change 12/3/97 Pinkfish
* * Pushed some of the yellow stuff down a hole and ate a bagel.
* *\/
*
* /\**
* * This method mixes the green in with our blue.
* * @param green the green object to mix.
* *\/
* void mixGreen(object green) {
* /\* Something wild and exciting! *\/
* } /\* mixGreen() *\/
*
* /\**
* * This method mixes the yellow in with our blue.
* * @param yellow the yellow object to mix.
* * @return returns a TRUE or FALSE depending on if the mix succeeded.
* * @example
* * mixYellow(12);
* *\/
* int mixYellow(object yellow) {
* } /\* mixYellow() *\/
*

* @see autodoc_file
* @see autodoc_nroff
