## NAME
       mmroff - cross-reference preprocessor for GNU roff mm macro package

## SYNOPSIS
       **mmroff** [**-x**] _groff-arguments_

## DESCRIPTION
       _mmroff_  is  a  simple  preprocessor for _groff_, used for expanding cross references in _mm_; see
       [_groff_mm_(7)](https://www.chedong.com/phpMan.php/man/groffmm/7/markdown).  _groff_ is executed twice, first with **-z** and **-rRef=1** to collect all cross  refer‐
       ences and then to do the real processing when the cross-reference file is up to date.

## OPTIONS
### -x
              file; it isn't always needed to have accurate cross references and by using  this  op‐
              tion _groff_ will only be run once.

## AUTHORS
       **mmroff** was written by Jörgen Hägg ⟨<jh@axis.se>⟩ of Lund, Sweden.
