3 # Common rules for Native Language Support (NLS)
5 # If some subdirectory of the source tree wants to provide NLS, it
6 # needs to contain a file 'nls.mk' with the following make variable
9 # CATALOG_NAME -- name of the message catalog (xxx.po); probably
11 # AVAIL_LANGUAGES -- list of languages that are provided/supported
12 # GETTEXT_FILES -- list of source files that contain message strings
13 # GETTEXT_TRIGGERS -- (optional) list of functions that contain
14 # translatable strings
15 # GETTEXT_FLAGS -- (optional) list of gettext --flag arguments to mark
16 # function arguments that contain C format strings
17 # (functions must be listed in TRIGGERS and FLAGS)
19 # That's all, the rest is done here, if --enable-nls was specified.
21 # The only user-visible targets here are 'init-po', to make an initial
22 # "blank" catalog from program sources, and 'update-po', which is to
23 # be called if the messages in the program source have changed, in
24 # order to merge the changes into the existing .po files.
27 # existence checked by Makefile.global; otherwise we won't get here
28 include $(srcdir)/nls.mk
30 # If user specified the languages he wants in --enable-nls=LANGUAGES,
31 # filter out the rest. Else use all available ones.
