BRL 2.2 released 2003-06-09

        * BRL now works with stock Kawa 1.7.  See the Kawa NEWS file

        * A define-path syntax facilitates use of URL path segments,
        with convenient validation like define-input.

        * A define-cookie syntax provides convenient cookie
        validation, and automatically sets a cookie with the final
        value of the local variable.

        * A brl-html-hidden syntax allows convenient passing of local
        variables along as hidden form variables.

        * A define-session syntax provides convenient access to
        session variables, and automatically sets them with the final
        value of the local variable.

        * Error messages are now XHTML-compliant, for better
        integration with Cocoon.

        * HTTP status 500 can optionally be sent upon errors, for
        better integration with systems that detect errors by status.

particularly database applications. It is based on Scheme, which makes
the syntax extremely simple yet powerful. This implementation is a
Java Servlet using the Kawa Scheme compiler.  For more information see
