Whatever, as long as there's no code duplication.
A very simple solution would be to have pkg_admin do a pkg compare, and
call that then. Of course the shared lib approach will work too.

The patch below adds a command "pmatch" to pkg_admin that allows checking
if a pkg name matches a pattern:

	pkg_admin pmatch pattern pkg

On exit, the return code is set. I guess this can be used as an idea on
how to implement other things. Important thing is that we do not duplicate
the code!
