 173    This is because the code in this directory is used to build a library which
 174    will be linked with code in other directories to form programs.  We want to
 175    maintain a seperate translation file for this directory however, rather
 176    than being forced to merge it with that of any program linked to libbfd.
 177    This is a library, so it cannot depend on the catalog currently loaded.
 178
 179    In order to do this, we have to make sure that when we extract messages we
 180    use the OPCODES domain rather than the domain of the program that included
 181    the bfd library, (eg OBJDUMP).  Hence we use dgettext (PACKAGE, String)
 182    and define PACKAGE to be 'bfd'.  (See the code in configure).  */
