        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.

        implementation.  Here is a list of its essential features: It's
        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.

        Pexpect is similar to the Don Libes "Expect" system, but Pexpect

        is basically a pattern matching system. It runs programs and
        watches output. When output matches a given pattern Pexpect can
        respond as if a human were typing responses. Pexpect can be used
        for automation, testing, and screen scraping. Pexpect can be
        used for automating interactive console applications such as
        ssh, ftp, passwd, telnet, etc. It can also be used to control
        web applications via "lynx", "w3m", or some other text-based web
        browser. Pexpect is pure Python. Unlike other Expect-like
        modules for Python Pexpect does not require TCL or Expect nor
        does it require C extensions to be compiled. It should work on
        any platform that supports the standard Python pty module.

        pysqlite is a DB-API 2.0-compliant database interface for SQLite.

        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.

        Python language or its standard library, thus showing that
