# Run a test with the WebRTC Chromium build.
# Should work on any machine with a camera.
#
# Method:
# - Start server
# - Start 2 browser tabs
# - Browser tab 1 captures camera
# - Both browsers sign in
# - Browser 1 calls browser 2
# - Browser 2 displays camera feed from browser 1
#

# Feel free to tweak this locally if your chrome build is somewhere else.
# The default assumes that it is in a folder called chromium two levels
# up from the project root ('trunk').
