# This script is one of the two main driver scripts for testing the bisector.
# It should be used to test the bisection tool, if you do NOT want to test
# the compiler wrapper (e.g. don't bother with POPULATE_GOOD & POPULATE_BAD
# stages).
#
# It makes sure the good & bad object directories exist (soft links); checks
# to see if it needs to compile the good & bad sources & populate the
# directories; does so if needed.
#
# Then it calls main-bisect-test, which runs the actual bisection tests. This
# script assumes it is being run from the parent directory.
#
# NOTE: Your PYTHONPATH environment variable needs to include both the
# toolchain-utils directory and the
# toolchain-utils/binary_search_tool directory for these testers to work.
