 The Common Workflow Language (CWL) is a specification for describing analysis
-workflows and tools that are portable and scalable across a variety of software
-and hardware environments, from workstations to cluster, cloud, and high
-performance computing (HPC) environments.  CWL is designed to meet the needs of
-data-intensive science, such as Bioinformatics, Medical Imaging, Astronomy,
-Physics, and Chemistry.
