The builder binary is the old continuous build client for the Go project. It is still used by a few builders, but most builders have been migrated to our newer build & test infrastructure.

-dashboard="https://build.golang.org": Go Dashboard Host The location of the Go Dashboard application to which Go Builder will report its results. -rev=N: Build revision N and exit -cmd="./all.bash": Build command (specify absolute or relative to go/src) This flag is overridden in the following conditions: - If the build key ends in -race, then race.bash or race.bat will be chosen. - If the build key begins with nacl, then nacltest.bash will be chosen. -v: Verbose logging
The key file should be located at $HOME/.gobuildkey or, for a builder-specific key, $HOME/.gobuildkey-$BUILDER (eg, $HOME/.gobuildkey-linux-amd64).
The build key file is a text file of the format:
