Re: scheme -> (X)HTML

[Francesco Salvestrini <salvestrini@gmail.com>]

Hi Paul,

Sorry for bothering you off the list but I've hit some troubles with guile 
mailing lists lately so I'm writing to you directly.

There's a package I've put on savannah that uses SXML (via guile) in order to 
build HTML. Maybe it could be of some help to you. This is its main URL:

	http://www.nongnu.org/sitetool

Maybe it worth a look.

NOTE: It is in its early stage of development so do not expect too much ;-)

Cheers,
Francesco
