Rattail: Software for Retailers
Welcome to the Rattail project.
There is, at long last, a Rattail Demo which is intended to show off various features of the software. It doesn't do much yet, but will be improved as the author has time.
Note that you should login as chuck / admin for full demo access.
Some documentation is maintained along with the various Python software packages; see here for that list.
There is still an older (crustier) wiki available also...proceed there at your own risk.
Please see the Rattail Trac for source code, bug tracker, etc.
