transaction-based software configuration management

 Aegis provides a framework within which a team of developers may
 work on many changes to a program independently, and Aegis
 coordinates integrating these changes back into the master source
 of the program, with as little disruption as possible.
 .
 Aegis simplifies the problems associated with multiple developers and
 development trees by using a transaction-based approach to version control,
 along with a web-browsable repository and an integrated testing
 mechanism.

 interface, and aegis-web for a web based user interface.
