"""Builds the AppRTC collider using the golang toolchain.

The golang toolchain is downloaded by download_golang.py. We use that here
to build the AppRTC collider server.

This script needs to know the path to the 'src' directory in apprtc, the
root directory of 'go', the root directory of 'hg' and the output_dir.
