files are available as ../directory/file. This means that if some file
in the plugin directory is requested, it must do a chdir("..") before
including any of the standard SquirrelMail files.

+Options
+-------
+
+It is possible to create your own options sections with plugins. There are
+three hooks you will need to use.
+
+1. options_link_and_description
+ This creates the link and has a description that are shown on the options
+ page. This should output HTML that looks like this:
+
+ -----cut here-----
+ function my_function() {
+ global $color
+ ?>
+ <table width=50% cellpadding=3 cellspacing=0 border=0 align=center>
+ <tr>
+ <td bgcolor="<? echo $color[9] ?>">
+ <a href="../plugins/YOUR_PLUGIN/YOUR_OPTIONS.php">YOUR OPTIONS NAME</a>
+ </td>
+ </tr>
+ <tr>
+ <td bgcolor="<? echo $color[0] ?>">
+ YOUR DESCRIPTION
+ </td>
+ </tr>
+ </table>
+ <?php
+ }
+ -----cut here-----
+
+2. options_save
+ Here is the code that you need to do to save your options in the
+ preference files or manipulate whatever data you are trying to change
+ through the options section. You can look at options.php for details
+ on how this is to be done.
+
+3. loading_prefs (optional)
+ If you are wanting to save preferences to the preference files, then
+ you need to do this step as well. Otherwise if you are manipulating
+ other data, ignore this step.
+
+ You should put the code in here that loads your preferences back
+ into usable variables. Examples of this can be found in the file
+ src/load_prefs.php
