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