This command locates the root of the repository containing the current working directory.

It then displays a S-expression containing several fields related to that repository and the current path.

- $(b,repo_root) : The root of the enclosing repo (absolute path).

- $(b,path_in_repo) : The path of the current directory related to the repo root (relative path).

- $(b,vcs_kind) : The kind of version control for the enclosing repository (git|hg).
