ACDK ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but instead of using Basic/C# or Java as programming language, it bases C++ as core implementation language. ACDK implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml and more, as well as technologies like flexible Allocator/Garbage Collection, Threading and Unicode. With the extensions of ACDK C++ objects are available for reflection, serialization, aspect oriented class attributes and [D]ynamic [M]ethod [I]nvocation. This DMI act as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, VBScript) and standard component technologies (CORBA, COM+).

Active Resources Active Resource attempts to provide a coherent wrapper object-relational mapping for REST web services. It follows the same philosophy as Active Record, in that one of its prime aims is to reduce the amount of code needed to map to these resources.

Apydia Apydia is an API reference documentation generator for Python. It's designed as an instantly serviceable replacement for Pudge's API-documentation generator. It won't generate complete websites from reST etc. like Pudge does, though - Apydia is only about the API.

Atrack Atrack is a ntrack / Bittorrent tracker designed from the ground up to run on Google's App Engine grid. Its main goals are:

• As small codebase as possible.
• As fast as possible.
• As low bandwidth usage as possible.
• As low memory usage as possible.
• For this it relies heavily (and almost completely) on memcached, no data is stored anywhere, and it lets memcached do most of the lifecycle management. Atrack also aims to respect your privacy: other than what is needed for the most basic tracking (hashes/keys and ip/ports) atrack gathers no information whatsoever. Beyond that no aggregate statistics are kept of anything (at least once the testing/debugging phase is over), and nothing is stored permanently anywhere, not even hashes and ip/ports, they are kept in memory until they are expired by memcached and never written to disk or any other kind of permanent storage.

Babel A collection of tools for internationalizing Python applications Babel is composed of two major parts:

• tools to build and work with gettext message catalogs
• a Python interface to the CLDR (Common Locale Data Repository), providing access to various locale display names, localized number and date formatting, etc.

Beanstalkc beanstalkc is a simple beanstalkd client library for Python. beanstalkd is a fast, distributed, in-memory workqueue service.

Bitstring bitstring is a pure Python module designed to help make the creation and analysis of binary data as simple and natural as possible. BitStrings can be constructed from integers (big and little endian), hex, octal, binary, strings or files. They can be sliced, joined, reversed, inserted into, overwritten, etc. with simple functions or slice notation. They can also be read from, searched and replaced, and navigated in, similar to a file or stream.

Bitten Bitten is a Python-based framework for collecting various software metrics via continuous integration. It builds on Trac to provide an integrated web-based user interface.

Booleano Booleano is an interpreter of boolean expressions, a library to define and run filters available as text (e.g., in a natural language) or in Python code. In order to handle text-based filters, Booleano ships with a fully-featured parser whose grammar is adaptive: Its properties can be overridden using simple configuration directives.

Bottle Bottle is a fast and simple WSGI web-framework for Python packed into a single file with no external dependencies.

C to C++ converter This packages is a set of Python scripts that perform each stage of code conversion from C to C++. First, header files are converted into classes and declarations become members. Then, references to variables and functions are transformed into references to attributes and methods of classes. Additional tools provided include a generator/updater of header files, and a trans-directory mover with update of include statements.

CMDln `cmdln.py` is an extension of Python's default `cmd.py` module that provides "a simple framework for writing line-oriented command interpreters". The idea (with both cmd.py and cmdln.py) is to be able to quickly build multi-sub-command tools (think cvs or svn) and/or simple interactive shells (think gdb or pdb). Cmdln's extensions make it more natural to write sub-commands, integrate optparse for simple option processing, and make having good command documentation easier.

CRCmod Python module for creating functions computing the Cyclic Redundancy Check (CRC). Any generating polynomial producing 8, 16, 24, 32, or 64 bit CRCs is allowed. Generated functions can be used in Python or C/C++ source code can be generated.

Carrot carrot is an AMQP messaging queue framework. AMQP is the Advanced Message Queuing Protocol, an open standard protocol for message orientation, queuing, routing, reliability and security. The aim of carrot is to make messaging in Python as easy as possible by providing a high-level interface for producing and consuming messages. At the same time it is a goal to re-use what is already available as much as possible. carrot has pluggable messaging back-ends, so it is possible to support several messaging systems. At the time of release, the py-amqplib based backend is considered suitable for production use. Several AMQP message broker implementations exists, including RabbitMQ, ZeroMQ and Apache ActiveMQ. You'll need to have one of these installed, personally we've been using RabbitMQ. Before you start playing with carrot, you should probably read up on AMQP, and you could start with the excellent article about using RabbitMQ under Python, Rabbits and warrens. For more detailed information, you can refer to the Wikipedia article about AMQP.

CodePY CodePy is a C/C++ metaprogramming toolkit for Python. It handles two aspects of native-code metaprogramming:

• Generating C/C++ source code.
• Compiling this source code and dynamically loading it into the Python interpreter.
• Both capabilities are meant to be used together, but also work on their own. In particular, the code generation facilities work well in conjunction with PyCuda. Dynamic compilation and linking are so far only supported in Linux with the GNU toolchain.

CodeTools The CodeTools project includes packages that simplify meta-programming and help the programmer separate data from code in Python. This library contains classes that allow defining simple snippets, or "blocks", of Python code, analyze variable dependencies in the code block, and use these dependencies to construct or restrict an execution graph. These (restricted) code blocks can then be executed in any namespace. However, this project also provides a Traits-event-enhanced namespace, called a "context", which can be used in place of a vanilla namespace to allow actions to be performed whenever variables are assigned or retrieved from the namespace. This project is used as the foundation for the BlockCanvas project.

Colubrid Colubrid is a WSGI request handler which simplifies python web development. If you've ever created a WSGI application without an framework or an request handler you know how stupid this can be.

ConfigObj A python module for ultra simple handling of configuration files. Also useful for human readable data persistence. Flexible and simple. ConfigObj is a simple but powerful config file reader and writer: an ini file round tripper. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files.

CouchDBKit CouchDB is a document oriented database. This is is a framework to allow your Python application to use CouchDB.

CouchDBlib This is a Python library for CouchDB. It provides a convenient high level interface for the CouchDB server. This package currently encompasses four primary modules:

• couchdb.client: the basic client library
• couchdb.design: management of design documents
• couchdb.schema: a higher-lever API for mapping between CouchDB documents and Python objects
• couchdb.view: a CouchDB view server that allows writing view functions in Python
