-This directory contains Andrew Kuchling's programmers guide to ZODB
-and ZEO.  It is taken from Andrew's zodb.sf.net project on
-SourceForge.  The SF version should be considered the canonical
-version, so don't make edits here for now.
-
-Eventually, we'll finish merging the two projects and then the version
-here will be the canonical one.  For now, we have to manually keep the
-two directories in sync.
