pyBit uses AMQP to create a distributed, cross-platform buildd toolkit to build packages using a collection of buildds, direct from various VCS clients. It is intended to support rapidly evolving software collections, and can support multiple VCS frontends and multiple build backends. Cross building is expected to be supported for some backends. The initial backend uses dpkg for Debian. pyBit includes support for cancelling selected builds and using multiple buildd clients per architecture, per platform, and per suite.
Meld is a visual diff and merge tool. It integrates with most version control systems. The diff viewer lets you edit files in place (diffs update dynamically), and a middle column shows detailed changes and allows merges. The margins show location of changes for easy browsing, and it also features a tabbed interface that allows you to open many diffs at once.
