The XML files in this directory are transformed into HTML
using the options.xsl style-sheet. The only effect of the style-sheet
is to transform tags of the form <command-option name="option"/> into
the standard text describing that options. The other tags in the XML files 
should be standard XHTML tags (HTML tags but with lower case tag names and 
mandatory closing tags). 

The options.xsl style-sheet contains the text describing the command options, 
packaged as template match directives. As you add options, add the text
describing the option to the options.xsl style-sheet, packaged as a
template match directive with a match property of the form 
"command-option[@name='option name']".  In the XML file you can import 
this text using tags of the form: <command-option name="option name"/>
