+# @BLURB: Manages build configuration for wxGTK-using packages.
+# @DESCRIPTION:
+#  This eclass sets up the proper environment for ebuilds using the wxGTK
+#  libraries.  Ebuilds using wxPython do not need to inherit this eclass.
+#
+#  More specifically, this eclass controls the configuration chosen by the
+#  /usr/bin/wx-config wrapper.
+#
+#  Using the eclass is simple:
+#
+#    - set WX_GTK_VER equal to a SLOT of wxGTK
+#    - call setup-wxwidgets()
+#
+#  The configuration chosen is based on the version required and the flags
+#  wxGTK was built with.

+# @FUNCTION:    setup-wxwidgets
+# @DESCRIPTION:
+#
+#  Call this in your ebuild to set up the environment for wxGTK.  Besides
+#  controlling the wx-config wrapper this exports WX_CONFIG containing
+#  the path to the config in case it needs to be passed to a build system.
+#
+#  In wxGTK-2.9 and later it also controls the level of debugging output
+#  from the libraries.  In these versions debugging features are enabled
+#  by default and need to be disabled at the package level.  Because this
+#  causes many warning dialogs to pop up during runtime we add -DNDEBUG to
+#  CPPFLAGS to disable debugging features (unless your ebuild has a debug
+#  USE flag and it's enabled).  If you don't like this behavior you can set
+#  WX_DISABLE_NDEBUG to override it.
+#
+#  See: http://docs.wxwidgets.org/trunk/overview_debugging.html
