+# @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
+# ${ESYSROOT}/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 in src_configure.
+# Besides controlling the wx-config wrapper, this exports WX_CONFIG containing
+# the path to the config in case it needs to be passed to the build system.
+#
+# This function also controls the level of debugging output from the libraries.
+# 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: https://docs.wxwidgets.org/trunk/overview_debugging.html
