Usage: $program FILE
Produce a version of the PostScript FILE with a protected call to the
PostScript operator \`setpagedevice'. Typical use is making FILE
print duplex, or on the manual tray etc.
Options:
-h, --help display this help and exit
-v, --version display version information and exit
-q, --quiet don't print informational messages
-o, --output=FILE save result in FILE. If FILE is \`-', send to stdout
-n, --no-fix don't run \`fixps' to fix PS problems in FILE
changequote(, )dnl
-S, --setpagedevice=KEY[:VALUE] pass a page device definition to output.
changequote([, ])dnl
Multiple values accumulate
-a, --at=PAGE insert the page device definitions at PAGE. Default
is PAGE=0, standing for the Document's Setup section
Shortcuts:
-m, --manualfeed alias for -SManualFeed:true
-s, --simplex alias for -SDuplex:false
-d, --duplex alias for -SDuplex:true -STumble:false
corresponds to Duplex, binding along the long edge
-t, --tumble alias for -SDuplex:true -STumble:true
corresponds to Duplex, binding along the short edge
Produced output is meant for PS level 2 printers.
