NAnt

NAnt is a free and open source software tool for automating software build processes. It is similar to Apache Ant, but targeted at the .NET environment rather than Java. The name NAnt comes from the fact that the tool is Not Ant.

NAnt requires one of the .NET frameworks (1.0, 1.1, 2.0, 3.5 or 4.0) or the third party Mono platform.
