# Leave in the file url-cards.ps a printable document consisting of
# $nup blocks of url and password.  This is useful for printing out
# (single-sided!) and handing out at a workshop that involves giving
# the participants EC2 instances.  The cards are ordered so that
# cutting the pages will produce sequential stacks.
