[wingide-users] How to use ActiveState's Python HTMLHelp file with Wing IDE

[Wingware Support]

Thanks.  Note that this does depend on python 2.5 being installed with 
the win32 extensions in c:\Python25. It can probably be made to work 
with ctypes to remove the dependence on the win32 extensions.  I mention 
this in case someone without these prerequisites wants to use it.

Cheers,

John
