This needs review as I am confused about how to keep depot_tools updated - with
update_depot_tools or with gclient?

For my local checkout `gclient sync` doesn't work.

>gclient sync
Error: client not configured; see 'gclient config'

>gclient config
Usage: gclient.py config [options] [url] [safesync url]

gclient.py: error: Inconsistent arguments. Use either --spec or one or 2 args

If you want to manually update it to develop with it, you can run `git
rebase-update` locally (or `git pull`-type lower level commands).

`git rebase-update` won't work, because glient.py creates .bat files.

Hm... I'm not sure what you mean? I use rebase-update pretty frequently. Maybe
you're thinking of committing .bat files with CQ which (still) doesn't support
windows line endings?

Oh, I see what you mean; if there's a new git version, the .bat files for it
wouldn't be created. 

lgtm, this is a lot better than before :)
