[ZDP] Zope Features doc

[Brian Hooper]

hi there!

i have been a silent lurker on the ZDP list for a while now, you all
are doing some great work!

i was looking at the Zope site today (well, like every day, i guess)
and i was noticing how much information there actually is already
there - for example, the Zope Features doc.  i think a lot of the
wording and examples in this document are really good, although a
little out of date; have you guys seen all of this, i think it might,
with some updating, be a good base for a doc, or could be integrated
usefully into the Z Book project... what does everyone think?
