quilt

Collection of bash scripts to ease working with patch files

quilt is a collection of bash scripts to manage a series of patches by keeping track of the changes each patch makes. Patches can be applied, un-applied, refreshed, etc. The key philosophical concept is that your primary output is patches. Not ".c" files, not ".h" files. But patches. So patches are the first-class object here. Quilt was originally based on Andrew Morton's patch scripts published on the Linux kernel mailing list.
