     16 # Usage:
     17 #
     18 # Source this file into your environment.  Then:
     19 #
     20 #    $ golden_builds sdk-sdk generic-eng generic-userdebug dream-eng
     21 # 
     22 # will build a set of combos.  This might take a while.  Then you can
     23 # go make changes, and run:
     24 #
     25 #    $ check_builds sdk-sdk generic-eng generic-userdebug dream-eng
     26 #
     27 # Go get dinner, and when you get back, there will be a file
     28 # test-builds/sizes.html that has a pretty chart of which files are
     29 # in which tree, and how big they are.  In that chart, cells for files
     30 # that are missing are red, and rows where the file sizes are not all
     31 # the same will be blue.
