+   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.
