/*
 Notes: ShowHelp uses section ids for displaying particular topics,
 but you might want to use a unique keyword to display a topic, instead.

 Section ids are specified as follows for the different formats.

 WinHelp

   The [MAP] section specifies the topic to integer id mapping, e.g.

   [MAP]
   #define intro       100
   #define functions   1
   #define classes     2
   #define about       3

   The identifier name corresponds to the label used for that topic.
   You could also put these in a .h file and #include it in both the MAP
   section and your C++ source.

   Note that Tex2RTF doesn't currently generate the MAP section automatically.

 MS HTML Help

   The [MAP] section specifies the HTML filename root to integer id mapping, e.g.

   [MAP]
   #define doc1       100
   #define doc3       1
   #define doc2       2
   #define doc4       3

   The identifier name corresponds to the HTML filename used for that topic.
   You could also put these in a .h file and #include it in both the MAP
   section and your C++ source.

   Note that Tex2RTF doesn't currently generate the MAP section automatically.

 Simple wxHTML Help and External HTML Help

   A wxhelp.map file is used, for example:

   0 wx.htm             ; wxWidgets: Help index; additional keywords like overview
   1 wx204.htm          ; wxWidgets Function Reference
   2 wx34.htm           ; wxWidgets Class Reference

   Note that Tex2RTF doesn't currently generate the MAP section automatically.

 Advanced HTML Help

   An extension to the .hhc file format is used, specifying a new parameter
   with name="ID":

   <OBJECT type="text/sitemap">
   <param name="Local" value="doc2.htm#classes">
   <param name="Name" value="Classes">
   <param name="ID" value=2>
   </OBJECT>

   Again, this is not generated automatically by Tex2RTF, though it could
   be added quite easily.

   Unfortunately adding the ID parameters appears to interfere with MS HTML Help,
   so you should not try to compile a .chm file from a .hhc file with
   this extension, or the contents will be messed up.
