Lightning talk from Bryan O'Sullivan aired at EuroPython 2006
This talk presents Mercurial Queue (mq), an extension to the SCM software Mercurial. Mq is used to manage a series of patches in the same way that quilt does. The main difference is its complete integration with source code management software, so that you can view the patches as changeset objects.
Mq adheres to the Mercurial philosophy: it is simple to use and blazingly fast. It can manage hundreds of patches applied to a 20,000 file repository.
