+# @DESCRIPTION:
+# Default pkg_setup function for packages that depends on qt3. If you have to
+# create ebuilds own pkg_setup in your ebuild, call qt3_pkg_setup in it.
+# This function uses two global vars from ebuild:
+# - QT3_BUILT_WITH_USE_CHECK - contains use flags that need to be turned on for
+#   =x11-libs/qt-3*
+# - QT3_OPTIONAL_BUILT_WITH_USE_CHECK - qt3 flags that provides some
+#   functionality, but can alternatively be disabled in ${CATEGORY}/${PN}
+#   (so qt3 don't have to be recompiled)
