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

 
 

-   // Note: these DisplaySection calls use ids that are specific to wxExtHelpController
-   // (on Unix). For WinHelp, we'd need to use different context ids.
+ 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             ; wxWindows: Help index; additional keywords like overview
+   1 wx204.htm          ; wxWindows Function Reference
+   2 wx34.htm           ; wxWindows 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.
