The Ruffus module is a lightweight way to add support
for running computational pipelines.

Computational pipelines are often conceptually quite simple, especially
if we breakdown the process into simple stages, or separate **tasks**.

Each stage or **task** in a computational pipeline is represented by a python function
Each python function can be called in parallel to run multiple **jobs**.

Ruffus was originally designed for use in bioinformatics to analyse multiple genome
data sets.
