# This script emulates the System V lp command using the Athena lpr
# command.  The emulation is not perfect; the known imperfections are:
#
# 	* The -s option is ignored, since lpr doesn't normally print
#	  output and doesn't have an option to suppress it when it
#	  does.
#
#	* The -m and -w options, which cause mail to be sent or a
#	  message to be written to the user when the print job is
#	  done, are both replaced with -z, which causes a zephyr to be
#	  sent to the user when the print job is done.
#
#	* All -o options are ignored (normally they are
#	  printer-specific options) except for "nobanner".
#
#	* Arguments to some options may be expanded twice for words and
#	  globbing.

# Parse command-line flags.
