nop [ -p? ] [ files ]
nop reads a stream of graphs and prints each in pretty-printed (canoni-
cal) format on stdout. If no files are given, it reads from stdin.
The following options are supported:
-p Produce no output - just check the input for valid DOT.
-? Print usage information.
If any errors occurred while processing any input, such as a file not
found or a file containing illegal DOT, a non-zero exit value is
returned. Otherwise, zero is returned.
