groff: grog
2.6.1 'grog'
------------
'grog' reads files, guesses which of the 'groff' preprocessors and/or
macro packages are required for formatting them, and prints the 'groff'
command including those options on the standard output. It generates
one or more of the options '-e', '-man', '-me', '-mm', '-mom', '-ms',
'-mdoc', '-mdoc-old', '-p', '-R', '-g', '-G', '-s', and '-t'.
A special file name '-' refers to the standard input. Specifying no
files also means to read the standard input. Any specified options are
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 and exit.
For example,
grog -Tdvi paper.ms
guesses the appropriate command to print 'paper.ms' and then prints it
to the command line after adding the '-Tdvi' option. For direct
execution, enclose the call to 'grog' in backquotes at the Unix shell
prompt:
`grog -Tdvi paper.ms` > paper.dvi
As seen in the example, it is still necessary to redirect the output to
something meaningful (i.e. either a file or a pager program like
'less').
