Command version number in manual page output prone to be forgot
at the release time, so it is best to remove it completely.

The help screen has now same notation as most of the GNU/Linux
utilities, e.g. if a option requires argument it is marked as
option=ARG. That enabled me to use help2man to make small nroff
fixes to manual page to unify it's outlook as well.
