nop


SYNOPSIS
       nop [ -p?  ] [ files ]

DESCRIPTION
       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.

OPTIONS
       The following options are supported:

       -p     Produce no output - just check the input for valid DOT.

       -?     Print usage information.

EXIT STATUS
       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.
