10"""Builds the AppRTC collider using the golang toolchain.
11
12The golang toolchain is downloaded by download_apprtc.py. We use that here
13to build the AppRTC collider server.
14
15This script needs to know the path to the 'src' directory in apprtc, the
16root directory of 'go' and the output_dir.
