Hi Ant,

Thanks for volunteering. I'm glad you like it, I've been using this 
little shell to start/stop my apps and found it quite easy to use so I 
thought it'd help others too.

If you want to help, I need more commands (to support apps made of 
multiple contribs etc), illustrated by the following example script:

=> install c1 http://foo.org/c.jar

=> install c2 http://foo.org/d.jar

=> install c3 http://foo.org/e.jar

=> installed
c1 http://foo.org/c.jar http://myns foo
c2 http://foo.org/d.jar http://myns bar
c3 http://foo.org/e.jar

=> installed c1
c1 http://foo.org/c.jar http://myns foo

=> validate c1
resolved c3
missing http://otherns x4 (a namespace provided by c4)

=> install c4 http://foo.org/f.jar

=> start nodeA c1 http://myns foo

=> start nodeB c2 http://myns bar

=> status
nodeA c1 http://myns foo
nodeB c2 http://myns bar

=> status nodeA
nodeA c1 http://myns foo

=> stop nodeA

=> stop nodeB

=> bye

In this example, c1 is a contribution URI, http://foo.org/c.jar its 
location, nodeA is a node name, http://myns foo is a composite qname.

I was going to code these commands myself as I'll need them mid of this 
week, but I could use your help as I'm quite busy with other things too.

So if you have time, do you think you could add the above commands 
sometime this week? That would really help me a lot!
