42# XXX Bugs:
43# . Our lpr command is not smart enough about dashes as input file names,
44#   they should indicate the use of standard input.
45# . Our lpr command should allow the Posix-compliant way of specifying
46#   options that take an argument; it currently requires the argument
47#   to follow the option immediately.
