# 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/gtk30.pot, and like this:
#
#   ./make-pot properties
#
# to generate po-properties/gtk30-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 gtk30 or gtk30-properties)
# XGETTEXT_KEYWORDS - --keyword arguments to pass to xgettext
