apt and deity

[Vincent Murphy <murphyv@wisdom.ucc.ie>]

I am interested in finding out about apt and deity. I would appreciate if
someone would inform me of a website or somewhere where I can get 
introductory information.

Specifically, i was wondering ring whether it would be possible for me to
install packages using http, thru a http proxy. I am inside a firewall,
and cannot ftp or NFS outside. Just so you know what kind of proxy I'm
talking about, I just put in it's hostname and port 80 in netscape, and it
works away fine.  Is it possible to use apt the same way?

Many thanks,
Vincent.
