                 Key: KARAF-170
                 URL: https://issues.apache.org/jira/browse/KARAF-170
             Project: Karaf
          Issue Type: Improvement
          Components: console
            Reporter: james strachan
             Fix For: 2.2.0


when using the org.apache.karaf.shell.console.Main class directly as a program 
on the command line (lets call it main for now) you can get help on a sub 
command as follows...

{code}
main foo --help
{code}

so it would be good to also support


{code}
main --help
{code}

Either that or we should add a help command so we can do

{code}
main help
{code}

or

{code}
main help foo
{code}
