# As the name implies, git-secrets heavily depends on git:
#
# a) the config is stored and fetched using 'git config'.
# b) the search is performed using 'git grep' (other search methods don't work
#    properly, see https://github.com/awslabs/git-secrets/issues/66)
#
# When we run in a CodeBuild build, we don't have a git repo, unfortunately. So
# when that's the case, 'git init' one on the spot, add all files to it (which
# because of the .gitignore will exclude dependencies and generated files) and
# then call 'git-secrets' as usual.
