# toarxiv.sh: Create a directory containing the pieces of perfbook
#	needed for an arxiv.org submission.  Run at the top level of
#	the perfbook source tree after typing "make".
#
# Usage: toarxiv.sh [ destdir ]
#
# The destdir argument defaults to "/tmp/perfbook".  If this already
# exists, the script complains and aborts.
