      longDescription = ''
        Nevow - Pronounced as the French "nouveau", or "noo-voh", Nevow
        is a web application construction kit written in Python.  It is
        designed to allow the programmer to express as much of the view
        logic as desired in Python, and includes a pure Python XML
        expression syntax named stan to facilitate this.  However it
        also provides rich support for designer-edited templates, using
        a very small XML attribute language to provide bi-directional
        template manipulation capability.

        Nevow also includes formless, a declarative syntax for
        specifying the types of method parameters and exposing these
        methods to the web.  Forms can be rendered automatically, and
        form posts will be validated and input coerced, rendering error
        pages if appropriate.  Once a form post has validated
        successfully, the method will be called with the coerced values.

        ASCII with \uXXXX escapes for unicode characters).
