-----------------------------------------+----------------------------------
 Chicken-setup should have a new option -clean (short form -C) which
 reliably cleans up artifacts left in the current directory from installing
 the specified egg, or from failed builds.  It is not an error to clean if
 there is nothing to do.

 Rationale: makes cleaning possible in a system-independent way, even in
 systems where "rm" and "rm -r" do not exist, and would work even if the
 current system of building eggs were to be changed.

 Example:  "chicken-setup -C myegg" would remove myegg.egg and the
 directory myegg.egg-dir.
