This PR adds a simple manpage for
flux-version(1)
(allowingversion
to appear in output offlux-help(1)
.Also, a quick hack is added to make
flux -V, --version
an alias forflux version
(suggested by @SteVwonder)It would be easy to just provide the flux-version manpage if the
flux -V
flag is a step too far.
