 142    This is because the code in this directory is used to build a library which
 143    will be linked with code in other directories to form programs.  We want to
 144    maintain a seperate translation file for this directory however, rather
 145    than being forced to merge it with that of any program linked to libbfd.
 146    This is a library, so it cannot depend on the catalog currently loaded.
 147
 148    In order to do this, we have to make sure that when we extract messages we
 149    use the OPCODES domain rather than the domain of the program that included
 150    the bfd library, (eg OBJDUMP).  Hence we use dgettext (PACKAGE, String)
 151    and define PACKAGE to be 'bfd'.  (See the code in configure).  */
