Actually that was just a use case.  Its main purpose is to list eggs,
AFAIK, we don't have a tool to do that.

Is it possible (and easy) to use -reinstall to install eggs on another
chicken's prefix?  Note that the example above we have different
installation prefixes (<new-prefix> and <old-prefix>).
