==============

A script to build clang from source.

```
usage: build-clang.py [-h] -c CONFIG [--clean]

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Clang configuration file
  --clean               Clean the build directory
```

Pre-requisites
--------------
* Working build toolchain.
* Subversion
* CMake
* Ninja
