* Flag `--print-invalid' in `nix-store --check-validity' to print out
  which paths specified on the command line are invalid (i.e., don't
  barf when encountering an invalid path, just print it).  This is
  useful for build-remote.pl to figure out which paths need to be
  copied to a remote machine.  (Currently we use rsync, but that's
  rather inefficient.)
