        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.

        implemented entirely in Python; It uses LR-parsing which is
        reasonably efficient and well suited for larger grammars; PLY
        provides most of the standard lex/yacc features including support for
        empty productions, precedence rules, error recovery, and support for
        ambiguous grammars; PLY is straightforward to use and provides very
        extensive error checking; PLY doesn't try to do anything more or less
        than provide the basic lex/yacc functionality.  In other words, it's
        not a large parsing framework or a component of some larger system.

        SQLite is a relational database management system contained in
        a relatively small C library.  It is a public domain project
        created by D. Richard Hipp.  Unlike the usual client-server
        paradigm, the SQLite engine is not a standalone process with
        which the program communicates, but is linked in and thus
        becomes an integral part of the program.  The library
        implements most of SQL-92 standard, including transactions,
        triggers and most of complex queries.

        pysqlite makes this powerful embedded SQL engine available to
        Python programmers.  It stays compatible with the Python
        database API specification 2.0 as much as possible, but also
        exposes most of SQLite's native API, so that it is for example
        possible to create user-defined SQL functions and aggregates
        in Python.
