All ezmlm-idx error messages are defines in errtxt.h, used at compile time. These can be changed for special situations, but we would advise against doing so. If you do for some reason produce such a translated file, we would appreciate if you sent a copy to the authors. NOTE: These do not affect error messages from programs that are not part of the ezmlm-idx package, nor of some subroutines used by ezmlm-idx programs (getconf_line.c comes to mind).
Hopefully, the error messages for all parts will be synchronized in later versions of ezmlm, and possibly handled from a run-time changeable separate file (maybe as a cdb database).
