Each line in the configuration file contains two parts:
Local path in your project, which can be either absolute path on your hard drive or it can be relative to the project root.
VCS path. This path points to a location under VCS root and is formatted according to TeamCity formatting rules.
It usually comprises identifier of the VCS repository and a path within this repository.
