xmlroff 0.6.0 is at http://xmlroff.org/download/xmlroff-0.6.0.tar.gz.
xmlroff 0.6.0 features a BSD license without a restriction against use in a nuclear facility, an
xmlroff.1 man page, and graphics rendering in the Cairo backend.
Thanks go to Jon Bosak and Mike Anastasio of Sun Microsystems for Sun’s re-release of its xmlroff source code under the no-restrictions BSD license and to lode leroy for graphics in the Cairo backend.
xmlroff is discussed on the email@example.com mailing list (subscription required) and on the
