If catfile does exist, its messages will be included in the new catfile . If set and message numbers collide, the new message text defined in msgfile will replace the old message text currently contained in catfile . Note that the fields of a message text source line are separated by a single blank character. Any other blank characters are considered as being part of the subsequent field. This line deletes message set n from an existing message catalog.
Any text following the set number is treated as a comment.
This line specifies an optional quote character c , which can be used to surround message-text so that trailing spaces or empty messages are visible in a message source line. Set numbers need not be contiguous. Any text following the set identifier is treated as a comment. Append translation info to the message catalog header. Only the newest date for a given identification is retained in the catalog.
