Vesta is a software configuration management system released by Compaq under the LGPL. Compaq claims that Vesta is a mature system and is the result of over 10 years of research and development at the Compaq/Digital Systems Research Center.

[edit] Features

Vesta has a number of unique capabilities, including:

A guarantee of precise build repeatability. Vesta builds are encapsulated in an environment cut off from the normal filesystem. They cannot use any files, settings, or other inputs that aren't under revision control.
Completely automatic dependency detection. The Vesta builder records file accesses made during builds, rather than having the user explicitly specify as with the popular Make tool.
A shared build cache. When multiple developers are using the system, they share the same pool of previously completed build work for re-use in future incremental builds. This saves time and resources across development teams.

Vesta is used by Intel for microprocessor development projects. They employ developers who actively work on the maintenance and development of Vesta.
