# a simple wrapper for the Manual class

"""GNUMed manuals in a HTML browser window

A very basic HTML browser with back/forward history buttons
with  the main pourpose of browsing the gnumed manuals
The manuals should reside where the manual_path points to.

@copyright: GPL
@thanks: this code has been heavily "borrowed" from
		 Robin Dunn's extraordinary wxPython sample
