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