    # The single slash form doesn't point to repository's root

    # directory anymore. Instead, when a single slash is passed

    # as argument through the command-line, it preserves its regular

    # meaning which is pointing the workstation's file system.

    # The path verification isn't appropriate here because this

    # function is commonly used inside variable assignments and flow

    # control doesn't take place in such situation. In case path

    # verification fails here, the script wouldn't end its execution

    # which contradicts the expected behaviour.
