 191    This is because the code in this directory is used to build a
 192    library which will be linked with code in other directories to form
 193    programs.  We want to maintain a seperate translation file for this
 194    directory however, rather than being forced to merge it with that
 195    of any program linked to libbfd.  This is a library, so it cannot
 196    depend on the catalog currently loaded.
 197
 198    In order to do this, we have to make sure that when we extract
 199    messages we use the BFD domain rather than the domain of the
 200    program that included the bfd library, (eg OBJDUMP).  Hence we use
 201    dgettext (PACKAGE, String) and define PACKAGE to be 'bfd'.
