# This script reformats source files using the clang-format utility.
#
# Files are changed in-place, so make sure you don't have anything open in an
# editor, and you may want to commit before formatting in case of awryness.
#
# This must be run on a clean repository to succeed
#
# Input parmameter must be full path to git repo to scan
