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.
