+# parse.c defines 3 macros:
+#
+# LOWINTEREST: It's not really interesting (deal with empty case is
+# defined in code but through use, it's not used) -> No_license_found
+# is returned on empty file...
+#
+# MEDINTEREST: Seems to define the proprietary ones
+#
+# INTERESTING: Seems to be the real FLOSS licenses
+#
+# Those macros takes 2 parameters, the license name and its weight of some kind
+# Grepping for those patterns to extract the licenses.
