	I just have a couple of questions about the SMTP side of Lua Socket.
The first, and likely easiest, question relates to HTML emails.  I do
not really the specifics of how they are sent, but I believe there are
just some slight differences in the headers between a plain text email
and a HTML email.  As such, is it possible to send HTML emails with Lua
Socket?  If so, what are the additional lines required for a basic HTML

	Secondly, while I have been able to successfully send regular emails
with Lua Socket, I have not yet managed to send an email with a simple
attachment.  The LED showing CPU activity glows almost the whole time,
but nothing ever happens --- I end up having to kill the script after
waiting several minutes.  I have copied my source below: I would imagine
I have made a simple error that can be quickly spotted by someone more
experienced.  If not, then any suggestions on how to debug this would be
greatly appreciated.
