Cog transforms files in a very simple way: it finds chunks of Python code embedded in them, executes the Python code, and inserts its output back into the original file. The file can contain whatever text you like around the Python code. It will usually be source code.

This is the Python parser that was originally developed for bzr-fastimport, but extracted so it can be used by other projects. It is currently used by bzr-fastimport and dulwich. hg-fastimport and git-remote-hg use a slightly modified version of it.

GeoTypes is a Python library that implements both the OpenGIS/PostGIS and standard PostgreSQL geometry types. It integrates with the psycopg Python/PostgreSQL interface. It provides implementations of all of the OpenGIS/PostGIS classes, except (x,y,m) and (x,y,z,m). It currently supports the EWKB, HEXEWKB, WKB, and WKT formats.

TGScheduler is a pure Python scheduler that can be used in any application. Tasks can be run in-process (within threads), forked (as new processes) or synchronously into the code. The scheduler makes it easy to have one-time or recurring tasks run as needed.

aspects is a lightweight approach to aspect oriented programming (AOP) in Python.The aspects.py library provides means to intercept function calls. Functions and methods (also in Python standard library and third party code) can be wrapped so that when they are called, the wrap is invoked first.

The aim of this module is to provide a common base representation of python source code for projects such as pychecker, pyreverse, pylint... Well, actually the development of this library is essentially governed by pylint's needs. It used to be called logilab-astng.

This Horde package provides a simple, functional caching API, with the option to store the cached data on the filesystem, in one of the PHP opcode cache systems (APC, eAcclerator, XCache, or Zend Performance Suite's content cache), memcached, or an SQL table.

To paraphrase the README: This is a Python language binding for the ORBit2 CORBA implementation. It aims to take advantage of new features found in ORBit2 to make language bindings more efficient. This includes: - Use of ORBit2 type libraries to generate stubs - use of the ORBit_small_invoke_stub() call for operation invocation, which allows for short circuited invocation on local objects.

The binary I/O stream class library presents a platform-independent way to access binary data streams in C++. The library is hardware independent in the form that it transparently converts between the different forms of machine-internal binary data representation. It further employs no special I/O protocol and can be used on arbitrary binary data sources.

PyProtocols extends the PEP 246 adapt() function with a new "declaration API" that lets you easily define your own protocols and adapters, and declare what adapters should be used to adapt what types, objects, or protocols. In addition to its own Interface type, PyProtocols can also use Twisted and Zope's Interface types too.
