# $Header: /cvsroot/pgsql/src/nls-global.mk,v 1.8 2003/09/14 22:40:38 petere Exp $
# Common rules for Native Language Support (NLS)
#
# If some subdirectory of the source tree wants to provide NLS, it
# needs to contain a file 'nls.mk' with the following make variable
# assignments:
#
# CATALOG_NAME -- name of the message catalog (xxx.po); probably
# name of the program
# AVAIL_LANGUAGES -- list of languages that are provided/supported
# GETTEXT_FILES -- list of source files that contain message strings
# GETTEXT_TRIGGERS -- (optional) list of functions that contain
# translatable strings
#
# That's all, the rest is done here, if --enable-nls was specified.
#
# The only user-visible targets here are 'init-po', to make an initial
# "blank" catalog from program sources, and 'update-po', which is to
# be called if the messages in the program source have changed, in
# order to merge the changes into the existing .po files.
# existence checked by Makefile.global; otherwise we won't get here
include $(srcdir)/nls.mk
# If user specified the languages he wants in --enable-nls=LANGUAGES,
# filter out the rest. Else use all available ones.
