# XXX Bugs:
|
|
# . Our lpr command is not smart enough about dashes as input file names,
|
|
# they should indicate the use of standard input.
|
|
# . Our /bin/sh is not Posix-1003.2 compliant in its getopts command;
|
|
# if the user specifies an option argument immediately after the
|
|
# option, the variable OPTIND will be set wrong. (This way of
|
|
# specifying option arguments is deprecated by Posix, but explicitly
|
|
# allowed.)
|
|
# . Our lpr command should allow the Posix-compliant way of specifying
|
|
# options that take an argument; it currently requires the argument
|
|
# to follow the option immediately.

# it, but the rationale mentions it as a possible future extension.
