    # The slash_path_empty plugin considers "/" as an empty path,

    # path.  This makes it so +r.is+ without an argument will match
    # a path of "/", and +r.is+ and verb methods such as +r.get+ and
    # +r.post+ will match if the path is "/" after the arguments
    # are processed.  This can make it easier to handle applications
    # where a trailing "/" in the path should be ignored.
