-# This Makefile fragment is meant to be included by packages that
-# require a wxGTK library.  wxGTK.mk will:
-#
-#	* set WXGTKBASE to the directory of wxGTK package
-#	* set WXGTK_TYPE to the version of wxGTK used.
-#
-# Because multiple versions of wxGTK cannot currently coexist, the
-# strategy is to use a single version, with each package building with
-# it if possible and failing otherwise.
-#
-# There are two variables that can be used to influence the selection of
-# the version of wxGTK.
-#
-# WXGTK_DEFAULT is a user-settable variable whose value is the default
-#	version of wxGTK, for example WXGTK28 or WXGTK30.
-#
-# WXGTK_ACCEPTED is a package-settable list of wxGTK versions
-#	that may be used by the package.
