NAME
          grog - guess options for groff command

     SYNOPSIS
          grog [ -option ] [ files...  ]

     DESCRIPTION
          grog reads files and guesses which of the groff(1) options
          -e, -man, -me, -mm, -ms, -p, -s, and -t are required for
          printing files, and prints the groff command including those
          options on the standard output.  A filename of - is taken to
          refer to the standard input.  If no files are specified the
          standard input will be read.  Any specified options will be
          included in the printed command.  No space is allowed
          between options and their arguments.  For example,

               `grog -Tdvi paper.ms`

          will guess the appropriate command to print paper.ms and
          then run it after adding the -Tdvi option.
