20210720 v1.16.0
- Note to Package Maintainers:
    TL;DR: `/man/jc.1.gz` and `/jc/man/jc.1.gz` are deprecated and only `/man/jc.1` should be used.

    The Man page in the PyPi source packages will be moving from `/jc/man/jc.1.gz` to `/man/jc.1`
    in version 1.17.0. For now the Man pages will be available in both locations, but be aware that
    the Man page at `/jc/man/jc.1.gz` is now considered deprecated.

    Also, starting in v1.17.0, the Man page will no longer be compressed in the source package,
    therefore `/man/jc.1.gz` should also be considered deprecated and will no longer be available
    after v1.17.0. Please use `/man/jc.1` and compress downstream if you would like.
