 # @FUNCTION: gst-plugins10_system_link
+# @USAGE: gst-plugins10_system_link gst-libs/gst/audio:gstreamer-audio [...]
 # @DESCRIPTION:
 # Walks through makefiles in order to make sure build will link against system
 # librairies.
+# Takes a list of path fragments and corresponding pkgconfig libraries
+# separated by colon (:). Will replace the path fragment by the output of
+# pkgconfig.
