/* Declarations of locale dependent catalog lookup functions.

     localealias.c    Possibly replace a locale name by another.
     explodename.c    Split a locale name into its various fields.
     l10nflist.c      Generate a list of filenames of possible message catalogs.
     finddomain.c     Find and open the relevant message catalogs.

   The main function _nl_find_domain() in finddomain.c is declared
