# This script basically follows the instructions to download an old version of Chromium: https://www.chromium.org/getting-involved/download-chromium
|
||
|
|
# 1) It retrieves the current stable version number from https://www.chromium.org/developers/calendar (via the https://omahaproxy.appspot.com/all file), e.g. 359700 for Chromium 48.
|
||
|
|
# 2) It checks the Travis cache for this specific version
|
||
|
|
# 3) If not available, it downloads and caches it, using the "decrement commit number" trick.
