Hi Ralf (et al),

Installing the ZendL library for Zend_Tool via a symlink, I get the
following error:

~/zf/Zend_Tool/library $ zf show version
An error has occured:
Action 'show' is not a valid action.

Replacing with the actual files eliminates the problem but this is
curious, and I'm wondering if you have a diagnosis / fix?

Also, I could do with a --help option or usage message for more of a
clue of what I can do...

Thanks,
Carlton
