 133    This is because the code in this directory is used to build a
 134    library which will be linked with code in other directories to form
 135    programs.  We want to maintain a separate translation file for this
 136    directory however, rather than being forced to merge it with that
 137    of any program linked to libbfd.  This is a library, so it cannot
 138    depend on the catalog currently loaded.
 139
 140    In order to do this, we have to make sure that when we extract
 141    messages we use the BFD domain rather than the domain of the
 142    program that included the bfd library, (eg OBJDUMP).  Hence we use
 143    dgettext (PACKAGE, String) and define PACKAGE to be 'bfd'.
