grog - guess options for groff command
grog [ -option ... ] [ files ... ]
DESCRIPTION
grog reads files and guesses which of the groff(1) options -e, -man, -me, -mm, -mom, -ms, -mdoc, -mdoc-old, -p,
-R, -g, -G, -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. The only options recognized are -C (which is also passed on) to enable com-
patibility mode, and -v to print the version number.
For example,
`grog -Tdvi paper.ms`
will guess the appropriate command to print paper.ms and then run it after adding the -Tdvi option.
