# This eclass helps you find the correct wx-config script so ebuilds
# can use gtk, gtk2 or gtk2+unicode versions of wxGTK

# FUNCTIONS:
# need-wxwidgets:
#   Arguments:
#     2.4: gtk gtk2 unicode !!! 2.4 is being removed from the tree !!!
#     2.6: gtk2 unicode base base-unicode mac mac-unicode
#
# set-wxconfig
#   Arguments: (wxGTK 2.4) wxgtk, wxgtk2, or wxgtk2u
#   Arguments: (wxGTK 2.6) gtk-ansi gtk2-ansi unicode base-ansi base-unicode mac-ansi mac-unicode
#   Note: Don't call this function directly from ebuilds
#
# check_wxuse
#   Check if wxGTK was built with the specified USE flag.
#   Usage:  check_wxuse <USE flag>
#	Note: for now, requires WX_GTK_VER to be set.
