# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description. Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in. You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

wxWidgets: wxWidgets (WxWidgets is a library to write portable GUI code)
wxWidgets:
wxWidgets: wxWidgets lets developers create applications for Win32, Mac OS X, 
wxWidgets: GTK+, X11, Motif, WinCE, and more using one codebase. It can be used 
wxWidgets: from languages such as C++, Python, Perl, and C#/.NET. Unlike other 
wxWidgets: cross-platform toolkits, wxWidgets applications look and feel native. 
wxWidgets: This is because wxWidgets uses the platform's own native controls 
wxWidgets: rather than emulating them. It's also extensive, free, open-source, 
wxWidgets: and mature.
