mmroff

MMROFF(1)						      General Commands Manual							 MMROFF(1)

NAME

       mmroff - reference preprocessor

SYNOPSIS

       mmroff [ -x ] groff_arguments

DESCRIPTION

       mmroff is a simple preprocessor for groff, it is used for expanding references in mm, see groff_mm(7).  groff is executed twice, first with
       -z and -rRef=1 to collect all references and then to do the real processing when the reference file is up to date.

       -x     Just create the reference file. This can be used to refresh the reference file, it isn't always needed to have  accurate	references
	      and by using this option groff will only be run once.
