%description
Implementation of the Future API on top of the 'batchtools' package. This
allows you to process futures, as defined by the 'future' package, in
parallel out of the box, not only on your local machine or ad-hoc cluster
of machines, but also via high-performance compute ('HPC') job schedulers
such as 'LSF', 'OpenLava', 'Slurm', 'SGE', and 'TORQUE' / 'PBS', e.g. 'y
<- future.apply::future_lapply(files, FUN = process)'.
