  15 # You can invoke this script like this:
  16 #   echo "1fda60c695b7a1bb7303f79a0b6d4b792db0efe0" | ./go.sh
  17 # This will build GCC and start the scripts in the bmks directory with
  18 # the default configuration.
  19 #
  20 # Invoke this script as a gearman worker like this:
  21 #   nohup gearman -h 10.236.48.91 -w -f tester ~/gcc/test/go.sh &
  22 # then you can distribute work using a todo file like this:
  23 #   gearman -b -h 10.236.48.91 -n -f tester < todo
  24 #
  25 # the format of each line in the todo file is "key config email" with
  26 # key a valid SHA1 object, config the symbolic name for the compiler
  27 # options to be used.  The minimal valid line contains only the SHA1
  28 # key, the default config is ofast, and no email is sent.  For example
  29 # the following would be a valid line in the todo file:
  30 #   820c090b60266f0102253822c3d108e05f135014 ofast foo@bar.com
  31 #
  32 # To retrieve a list of SHA1 for all the patches containing "config/i386"
  33 # in the last 500 commits, use this command:
  34 #   git log --pretty=format:%H --grep="config/i386" HEAD~500..HEAD
  35 #
  36 # To fetch the tags from the test machines, one can use
  37 #   git fetch --tags testmachine
