"""Android bisector to bisect local build commits.

Example:
  $ ./bisect_android_repo.py init --old rev1 --new rev2 --android_root ~/android
  $ ./bisect_android_repo.py config switch ./switch_arc_localbuild.py
  $ ./bisect_android_repo.py config eval ./eval-manually.sh
  $ ./bisect_android_repo.py run

When running switcher and evaluator, following environment variables
will be set:
  ANDROID_BRANCH (e.g. git_mnc-dr-arc-dev),
  ANDROID_FLAVOR (e.g. cheets_x86-user),
  ANDROID_ROOT,
  DUT (e.g. samus-dut, if available).
