    # Update messages_xx.po and messages_xx.class files,
    # from both java and jsp sources.
    
    # Requires installed programs xgettext, msgfmt, msgmerge, and find.
    
    #
    # usage:
    #    bundle-messages.sh (generates the resource bundle from the .po file)
    #    bundle-messages.sh -p (updates the .po file from the source tags, then generates the resource bundle)
