<!--
Presents for building wxWidgets applications using Autoconf or GNU toosets.
See wx.bkl for platform-independent notes.

Usage:
    Options WX_CPPFLAGS, WX_CFLAGS, WX_CXXFLAGS, WX_LIBS are defined.


Format-specific notes:

* autoconf:
        Beware that you have to use AM_OPTIONS_WXCONFIG and
        AM_PATH_WXCONFIG in your configure.in!
