# Usage:
#
# Source this file into your environment.  Then:
#
#    $ golden_builds sdk-sdk generic-eng generic-userdebug dream-eng
# 
# will build a set of combos.  This might take a while.  Then you can
# go make changes, and run:
#
#    $ check_builds sdk-sdk generic-eng generic-userdebug dream-eng
#
# Go get dinner, and when you get back, there will be a file
# test-builds/sizes.html that has a pretty chart of which files are
# in which tree, and how big they are.  In that chart, cells for files
# that are missing are red, and rows where the file sizes are not all
# the same will be blue.
