This tool creates a tarball with all the sources, but without .svn directories.
It can also remove files which are not strictly required for build, so that
the resulting tarball can be reasonably small (last time it was ~110 MB).
Example usage (make sure gclient is in your PATH):
export_tarball.py /foo/bar
The above will create file /foo/bar.tar.bz2.
