# General Kallithea URL handling

    """Emulate pylons.url in providing a wrapper around routes.url

    This code was added during migration from Pylons to Turbogears2. Pylons

    already provided a wrapper like this, but Turbogears2 does not.

    When the routing of Kallithea is changed to use less Routes and more

    Turbogears2-style routing, this class may disappear or change.

    url() (the __call__ method) returns the URL based on a route name and

    arguments.

    url.current() returns the URL of the current page with arguments applied.

    Refer to documentation of Routes for details:

    https://routes.readthedocs.io/en/latest/generating.html#generation
