Configurable embedded Linux firmware update creator and runner

fwup is a configurable image-based software update utility for embedded Linux-based systems. It primarily supports software upgrade strategies that update entire root filesystem images at once. This includes strategies like swapping back and forth between A and B partitions, recovery partitions, and various trial update/failback scenarios. All software update information is combined into a ZIP archive that may optionally be cryptographically signed. fwup has minimal dependencies and runtime requirements.
