  (synopsis
    "Snakemake is a workflow management system that aims to reduce the 
complexity of creating workflows by providing a fast and comfortable execution 
environment, together with a clean and modern specification language in python 
style. Snakemake workflows are essentially Python scripts extended by 
declarative code to define rules. Rules describe how to create output files 
from input files.")
