Adds ../... ⇒ ... symlinks to a directory and all its children.
Expected to be combined with an anchor link . ⇒ ... somewhere below the directory.
Allows .../style/page/css style references in pages accessing the repository.
Avoids the use of relative paths, '..', for files that move around (or are accessible via symlink).
Avoids absolule paths, '/', for projects that are hosted at multiple urls.

 Usage: $0 <root directory>
