| # Use this to use git bisect with prebuilt binary artifacts. To use, first copy the script somewhere |
| # outside of the source tree (so git bisect won't mess with it) then run the following commands: |
| # git bisect start <bad> <good> |
| # git bisect run PATH_TO/bisect-helper <optional additional args to run-zircon> |
| # The script will download the prebuilt zircon.bin associated with each commit, if it exists, and |
| # start it up in qemu. After qemu exits, the script will ask if the build is good or bad. Type 'y' |
| # or 'n' and the bisect will proceed. |
