 156    This is because the code in this directory is used to build a
 157    library which will be linked with code in other directories to form
 158    programs.  We want to maintain a separate translation file for this
 159    directory however, rather than being forced to merge it with that
 160    of any program linked to libbfd.  This is a library, so it cannot
 161    depend on the catalog currently loaded.
 162
 163    In order to do this, we have to make sure that when we extract
 164    messages we use the BFD domain rather than the domain of the
 165    program that included the bfd library, (eg OBJDUMP).  Hence we use
 166    dgettext (PACKAGE, String) and define PACKAGE to be 'bfd'.
