 Description: As a successor of the packages BatchJobs and BatchExperiments,
     batchtools provides a parallel implementation of the Map function
-    for high performance computing systems managed by schedulers (LSF, OpenLava,
-    SGE, Slurm, Torque, Docker Swarm).

     A multicore and socket mode allow the parallelization on a local machines,
     and multiple machines can be hooked up via SSH to create a makeshift cluster.
     Moreover, the package provides an abstraction mechanism to define
