Summary : A parallel remote execution system
License : ASL 2.0
Description : Salt is a distributed remote execution system used to execute commands and
: query data. It was developed in order to bring the best solutions found in
: the world of remote execution together and make them better, faster and more
: malleable. Salt accomplishes this via its ability to handle larger loads of
: information, and not just dozens, but hundreds or even thousands of individual
: servers, handle them quickly and through a simple and manageable interface.
