Some answers to common commit-queue questions.

=== Q: What do the commit-queue states mean? ===

commit-queue+ // Patch is 100% ready for commit, queue should land it.  (Moral equivalent of committing yourself.)
commit-queue- // Patch needs manual landing (set this when you don't want any chance of auto-commit)
commit-queue? // Set by non-committers to ask someone to approve their patch for auto-commit.


=== Q: Who can set commit-queue+ or review+? ===

bugzilla-tool validates that the flag setters are committers/reviewers using:
http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/modules/committers.py


=== Q: How long until a patch lands after I set commit-queue+? ===

Generally about 15 minutes.  Depends on if commit-queue is running or not.


=== Q:  What checks does commit-queue do before landing? ===

Everything "bugzilla-tool land-patches" does.  Which is build (on Mac) and then run-webkit-tests.  If you would like it to do more, please file bugs and post patches to bugzilla-tool! :)


=== Q: When I review a patch, should I set commit-queue+? ===

Yes.  Unless the patch-poster is a committer or you want to commit it yourself.


=== Q:  When I don't want my patch to be auto-landed, what should I do? ===

You don't need to do anything.  Only commit-queue+ patches are auto-landed.  Setting commit-queue- will make extra-sure.


=== Q: If I want my patch landed, and I'm not a committer, what do I do? ===

Set "commit-queue=?".  A committer can set it to commit-queue+
