grog − guess options for groff command

grog [ option ... ] [ ]

grog reads files and guesses which of the options and are
required for printing 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 compatibility mode, and −v to print the version
number.

For example,

     paper.ms‘‘grog−Tdvi

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