 """Entry point for both build and try bots.
 
 This script is invoked from XXX, usually without arguments
 to package an SDK. It automatically determines whether
 this SDK is for mac, win, linux.
 
 The script inspects the following environment variables:
 
 BUILDBOT_BUILDERNAME to determine whether the script is run locally
 and whether it should upload an SDK to file storage (GSTORE)
