   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
   7 # assignments:
   8 #
   9 # CATALOG_NAME          -- name of the message catalog (xxx.po); probably
  10 #                          name of the program
  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)
  18 #
  19 # That's all, the rest is done here, if --enable-nls was specified.
  20 #
  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.
