[xmlroff] Reference manual and test results on xmlroff website

[Tony G. <Ton...@Su...>]

In advance of the xmlroff 0.3.1 release (which should be this
weekend), I have added the xmlroff 0.3.1 reference manual and test
results report to the xmlroff website.

Comments and suggestions for improvements are welcome.

I have also added a 'Ports' page, which currently only lists the
FreeBSD port.

Regards,


Tony.
