for Mercurial VCS, where does the agent check out the repo?

Using TeamCity 6.5,

I have the following configuration:



When I go to that folder on the agent there is no local repo, (no hg folders)

How does this work, does the agent even checkout a copy of the repo?

The reason for asking is I want to pass other properties of the hg repo to the build agent (eg the revision number)
