"FAKE - F# Make" is a cross platform build automation system. Due to its integration in F#, all benefits of the .NET Framework and functional programming can be used, including the extensive class library, powerful debuggers and integrated development environments like Visual Studio or MonoDevelop, which provide syntax highlighting and code completion.
The new DSL was designed to be succinct, typed, declarative, extensible and easy to use. For instance custom build tasks can be added simply by referencing .NET assemblies and using the corresponding classes.
