Lightning talk from Brian 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 pile of patch the same way quilt works. The main difference is the complete integration with source code management software that lets you view the patches as a changeset object.
Mq adhere to the Mercurial philosophy, it is simple to use and blazingly fast: it can manage hundreds of patches applied to a 20k files repository.
