Running jar without commands shows:

Usage: jar {ctxui}[vfm0Me] [jar-file] [manifest-file] [entry-point] [-C dir] files ...

This doesn't show the correct usage of the -p option (included in option lists)

The usage should be something like:

Usage: jar {ctxui}[vfm0Me] [jar-file] [manifest-file] [entry-point] [profile-name] [-C dir] files ...

or

Usage: jar {ctxui}[vfm0Me] [jar-file] [manifest-file] [entry-point] [compact{123}] [-C dir] files ...
