perl module to access XPG4 message catalog functions

 Locale::Msgcat is a small perl module for systems which support the XPG4
 message catalog functions : catopen(3), catgets(3) and catclose(3).
 .
 The module can be used to internationalize a perl program. Messages
 inside a catalog are identified by integers (unlike gettext which uses the
 English string as identifier).
