+# requires:
+# - CATALOG_NAME: name of the catalog (name of the library or program)
+#                 will be installed as $(CATALOG_NAME).po in the localedir
+# - GETTEXT_LANGUAGES: list of languages supported
+# - GETTEXT_FILES: list of source files that contain message strings
+# - GETTEXT_TRIGGERS: (optional) list of functions/macros that contain
+#                     translatable strings
+#
+# provides:
+# - target: init-po
+# - target: merge-po
