viewing sgml articles

[Dru]

What's the easiest way for an end-user to view the SGML articles in
/usr/doc? Is there a viewer, or do they have to be converted to say, html
first? I know they're mirrored online, but it would be nice to have the
ability to read off-line.

I tried installing textproc/sgmlformat and running:

sgmlfmt -d docbook -f html article.sgml

but it failed with tons of errors. The same command without -d also
failed.

Any advice?
