        Generate a document from a document template.

        The document will be generated by inserting values into the
        format string specified when the document template was
        created.  Values are inserted using standard python named
        string formats.

        The optional argument 'client' is used to specify a object
        containing values to be looked up.  Values will be looked up
        using getattr, so inheritence of values is supported.  Note
        that names beginning with '_' will not be looked up from the
        client.

        The optional argument, 'mapping' is used to specify a mapping
        object containing values to be inserted.

        Values to be inserted may also be specified using keyword
        arguments.

        Values will be inserted from one of several sources.  The
        sources, in the order in which they are consulted, are:
