[Zope-ZEO] Alpha release of ZODB programming guide

[Andrew Kuchling]

For what seems like half an eternity, I've been working on a ZODB
programming guide, written for Python programmers who want to use the
ZODB to store data.  The document is placed under the GNU Free
Documentation License.  It's still far from being finished, but while
on vacation I filled it out enough to make it alpha-worthy, though
note that there are still empty sections.  Please take a look at:

http://www.amk.ca/zodb/guide/

What I'd like right now:
     * Suggestions for topics that should be covered.  This would be
the most helpful.

     * Comments on the organization (ordering of chapters, topics, &c.)

     * Reporting errors and inaccuracies would also be helpful, but
are less important at the moment.  Getting the outline correct
is my primary concern at the moment.
