Snakemake is a workflow engine that provides a readable Python-based workflow definition
language and a powerful execution environment that scales from single-core workstations to
compute clusters without modifying the workflow. It is the first system to support the use of
automatically inferred multiple named wildcards (or variables) in input and output filenames.
