To use mom effectively, you should have the following:

1. a)  For mom versions 1.2-x and higher, optimally, you should have
       groff 1.19.2 or later installed, although mom 1.2-x and
       higher *should* work just as well with groff 1.18 and 1.19.
    b) For mom version 1.1.9, version 1.19 or later of groff, although
       mom 1.1.9 *should* work with groff 1.18 (no promises, though). 
    c) For mom v. 1.1.3 to 1.1.8, version 1.18 or later of groff; for
       versions of mom earlier than 1.1.3, version 1.17-2 of groff.

2.  A functioning print system; in GNU/Linux, that means lpr/
    lprng/cups or similar, with appropriate filters to output
    PostScript documents.

3.  In GNU/Linux, a working X server (not strictly necessary, but
    advisable).

4.  Working versions of gs (ghostscript) and gv (ghostview).

The documentation is written in html, so a browser (text-onlies
are just fine) or an editor capable of rendering html and
following links is a good idea, too.  The best way of using
the documentation is to open the table of contents file
(mom-<version>/momdoc/toc.html), and go from there.
