| # 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. |
