psycopg is a PostgreSQL database adapter for the Python programming language. Its main advantages are that it supports the full Python DBAPI 2.0 and it is thread safe at level 2. It was designed for heavily multi-threaded applications that create and destroy lots of cursors and make a conspicuous number of concurrent INSERTs or UPDATEs. The psycopg distribution includes ZPsycopgDA, a Zope Database Adapter.
The pure::variants Eclipse plugin supports development and variant management for software product lines with many product variants. pure::variants is completely model-based. It uses feature models for variability and commonality modeling. It supports creation, management, and evaluation of all necessary models, and uses XML based data formats. It includes a model transformer, which permits the creation of product variants directly from customizable components.
py-setproctitle is a library that allows a Python process to change its title, as displayed by system tools such as ps and top. Changing the title is useful in multi-process systems, for example when a master process is forked: changing the child's title allows you to identify the task each process is busy with. It is based on PostgreSQL's multi-platform implementation.
