Prophet is a lightweight schemaless database designed for peer-to-peer
replication and disconnected operation. Prophet keeps a full copy of
your data and (history) on your laptop, desktop or server. Prophet syncs
when you want it to, so you can use Prophet-backed applications whether
or not you have network.

SD (Simple Defects) is a peer-to-peer issue tracking system built on top of
Prophet. In addition to being a full-fledged distributed bug tracker, SD
can also bidirectionally sync with your RT, Hiveminder, Trac, GitHub or
Google Code issue tracker. 

Today marks the public release of "Cavil", the first versions of 
SD and Prophet which are ready for general use (though we've been using
SD to keep track of its own bugs for over a year).  Cavil is the 
culmination of 16 months of work and includes contributions from 
at least 20 developers:

A. Christine Spang, Alec Clews, Alex Vandiver, Arjen Laarhoven, c9s,
Casey West, Chia-liang Kao, Florian Ragwitz, Franck Cuny, Hans Dieter
Pearcey, Kang-min Liu, Kevin Falcone, Robert Krimen, Ruslan Zakirov,
Shawn Moore, Simon Wistow, sunnavy, Will Thompson, Yanick Champoux

Two contributors deserve special mention:

First, I'd like to thank Christine Spang. Over the past two summers,
she's done an astonishing job of making SD (and Prophet) friendlier and
easier to use, better documented and better tested.  She successfully got
us from "oh yeah, we should have a public release eventually" to today.
Thanks, Christine!

Second, I'd like to thank my partner in crime Chia-liang Kao. CL and I
designed and wrote 8000 lines of code which formed the core of what 
became Prophet and SD over the course of a marathon 8 day hackathon.

Prophet and SD should be considered "beta" quality software. They're 
unlikely to lose data and we've found that they work well for us. 
Database formats are considered to be stable and we'll go to great lengths
to ensure upgradability to new released versions from today forward.

SD supports custom ticket properties, comments and attachments. It uses
Prophet's "social" conflict resolution system to ease collaborative
work and keep full change history for each and every ticket update. SD
ships with both a web interface and a scriptable CLI.  It integrates
with git and Darcs.  In addition to the sync plugins mentioned above,
SD ships with read-only support for Redmine. A bidirectional Lighthouse
sync plugin is forthcoming.
