# This script generates statistics (build size, speed) for successive
# revisions of the code. It checks out git commits one an a time, compiles
# various ports to determine their size, and runs pystone on the unix port.
# Results are collected in the output file.
#
# Note: you will need to copy this file out of the tools directory before
# executing because it does not exist in old revisions of the repository.
# check that we are in the root directory of the repository
