mon-contrib 1.0+dfsg-3 (s390x binary) in ubuntu xenial

 mon-contrib is the mon /contrib archive. It contains user-submitted
 add-ons to mon, which are not included in the main mon distribution.
 .
 Most submissions are not checked by the archive maintainers for quality
 and some may not work, or work how you expect them to (most are quite
 good, though).
 .
 If you have something to contribute, either a new submission or a patch
 to another contrib'ed item, great! Please read the contrib guidelines to
 speed up the inclusion of your submission in the archives.
