# This script builds two Bazel classes which output the default checks in
# the Errorprone versions in Soong and Bazel.
# It then runs a python script that generates a file of flags that can be
# applied to Bazel that will ensure Bazel has the same default bugprone patterns
# as Soong's version of Errorprone.
#
#
# Usage: errorProneCompatibilityFlags.sh  <path to repository root>
