	Hi all,

	Well, based on some quick inspections on the that I checked out from
the mercurial repository this afternoon, it seems that the HT support
has been already implemented. :-)

	Thus, here is a suggestion, it would be nice to make more details
available about who is doing what and in which phase of development
things are, this information could avoid duplicated efforts.

	Thanks,
	Eli
