# I'd like to implement those:
#
# * -v      Turn on verbose output.
#   -I      If any installation scripts (pre-install or post-install) exist
#           for a given package, do not execute them.
#   -n      Don't actually install a package, just report the steps that
#           would be taken if it was.
#   -r      Use the remote fetching feature.  This will determine the appro-
#           priate objformat and release and then fetch and install the pack-
#           age.
