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