# 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.
