utility to generate .mender artifacts

 Mender Artifacts Library Mender is an open source over-the-air (OTA)
 software updater for embedded Linux devices. Mender comprises a client
 running at the embedded device, as well as a server that manages
 deployments across many devices.
 .
 This package contains the mender-artifact program which is used to generate
 the artifacts needed for mender OTA updates. The artifacts are generated
 from your existing ext4 rootfs image that you built for direct device
 deployments.
