| # for example, can execute this from hudson (with hudson |
| # lock) before promoting to staging directory, to make |
| # sure another build doesn't start while promoting, thereby |
| # erasing the build we are promoting. |
| |
| # to end lock, the lockfile must be removed, which can be |
| # done manually, or as part of the script work |
| # There is a one-hour time-out built in, which should be plenty |
