Don't see any source after Bazaar branch

[FreeBeer]

I'm trying to setup a development environment by following the Calibre website instructions. I installed Bazaar and I do the "bzr branch lp:calibre" in a C:\projects directory where I keep my projects. It chugs away, showing progress and eventually says "Branched 13146 revisions." There is now a C:\projects\calibre directory and I eagerly look inside. There is only a .bzr subdirectory. No sign of code like a src directory. I can see inside the .bzr that there is a repository with pack files which I assume are compressed source, but I was expecting a decompressed tree of calibre source in C:\projects\calibre. I've looked around to see if Bazaar made some other directory somewhere but I can't find one. Am I supposed to do something else after the branch? (this is all on Windows 7)

The bzr.log file seems happy with what it did:
...

bzr branch should get you the code, but if you're having trouble with it, just use the source tarball.
