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