* that if a IVersionControl * manages a directory, then it also manages
* all the files and all the subdirectories.
* It works by asking all IVersionControl * if they manage the file, and ask
* for the topmost directory it manages. This information is cached and
* VCSManager thus knows pretty fast which IVersionControl * is responsible.
* 2) Passes on the changes from the version controls caused by updating or
* branching repositories and routes them to its signals (repositoryChanged,
* filesChanged). */
