 # Copyright (c) 2009 The Chromium OS Authors. All rights reserved.
 # Distributed under the terms of the GNU General Public License v2
 
 # Usage: by default, downloads chromium browser from the build server.
 # If CHROME_ORIGIN is set to one of {SERVER_SOURCE, LOCAL_SOURCE},
 # The build comes from the chromimum source repository (gclient sync), \
 # build server, locally provided source, or locally provided binary
 # If you are using SERVER_SOURCE, a gclient tempalte file that is in the files
 # directory, which will be copied automatically during the build and used as
 # the .gclient for 'gclient sync'
 # If building from LOCAL_SOURCE or LOCCAL_BINARY specifying BUILDTYPE
 # will allow you to specify "Debug" or another build type; "Release" is
 # the default.
 # If getting it from the build server, setting CHROME_VERSION to the build
 # revision will pull that version, otherwise latest will be pulled.
 
 # gclient is expected to be in ~/depot_tools if EGCLIENT is not set
 # to gclient path.
