+# This script extracts the typical xgettext invokation out of
+# po/Makefile.in.in, in order for it to be available as a shell
+# command without the need to autogen first. This is needed for
+# translation tools such as the damn lies website.
+#
+# Call this from your GTK+ checkout directory, like this:
+#
+#   ./make-pot
+#
+# to generate po/gtk40.pot, and like this:
+#
+#   ./make-pot properties
+#
+# to generate po-properties/gtk40-properties.pot.
+#
+# Various things can be passed in by environment variables, which
+# are heavily inspired by the variables used in po/Makefile.in.in:
+#
+# XGETTEXT - path of the xgettext binary
+# top_srcdir - the location of the GTK+ checkout
+# srcdir - the directory where POTFILES.in is located (defaults to
+#          $top_srcdir/po or $top_srcdir/po-properties)
+# GETTEXT_PACKAGE - the gettext domain, used for naming the resulting
+#          .pot file (defaults to gtk40 or gtk40-properties)
+# XGETTEXT_KEYWORDS - --keyword arguments to pass to xgettext
