-- | @transient-universe@ extends the seamless composability of concurrent
-- multi-threaded programs provided by
-- <https://github.com/transient-haskell/transient transient>
-- to a multi-node cloud.  Distributed concurrent programs are created and
-- composed seamlessly and effortlessly as if they were written for a single
-- node.  @transient-universe@ has diverse applications from simple distributed
-- applications to massively parallel and distributed map-reduce problems.  If
-- you are considering Apache Spark or Cloud Haskell then transient might be a
-- simpler yet better solution for you.
--
-- Transient makes it easy to write composable, distributed event driven
-- reactive UI applications with client side and server side code composed
-- freely in the same application. For example,
-- <https://hackage.haskell.org/package/axiom Axiom> is a transient based
-- unified client and server side web application framework that provides a
-- better programming model and composability compared to frameworks like
-- ReactJS.
--
-- = Overview
--
-- The 'Cloud' monad adds the following facilities to complement the 'TransIO'
-- monad:
--
-- * Create a distributed compute cluster of nodes
-- * Move computations across nodes at any point during computation
-- * Run computations on multiple nodes in parallel
