# python makes importing files with dashes hard, sorry.  Renaming would
# allow us to simplify this to
#   import git_repo_filter
# However, since git style commands are dashed and git-filter-repo is used more
# as a tool than a library, renaming is not an option, so import is 5 lines:
import imp
import sys
sys.dont_write_bytecode = True # .pyc generation -> ugly 'git-filter-repoc' files
with open("../../../git-filter-repo") as f:
  repo_filter = imp.load_source('repo_filter', "git-filter-repo", f)
