=== Pushing Directly ===
It's also possible to push to try directly from hg (for now). This might be required if you're using [https://www.mercurial-scm.org/wiki/MqExtension mercurial queues]. In this case, the only way to select tasks if is by manually adding try syntax to your commit message:
$ hg commit -m "try: -b o -p linux64 -u mochitest"
