 **shake-language-c** is a cross-platform build system based on the [Shake](https://github.com/ndmitchell/shake) Haskell library. The focus is on cross-compilation of *C*, *C++* and *Objective C* source code to various target platforms. Currently supported target platforms are *iOS*, *Android NDK*, *Google Portable Native Client*, *MacOS X*, *Linux* and *Windows* (*MinGW*). Supported host platforms are *MacOS X*, *Linux* and *Windows*.
