"""
 
2
wxPython can use html files for online help or other forms of
 
3
documentation for your application.  The help can be organized as a
 
4
collection of books, and there is a help viewer available that enables
 
5
the user to browse by book, via an index or full text search.  The
 
6
format of the contents and index files are similar to Microsoft
 
7
HtmlHelp.
