If I understand well, it is "just" a R front-end to cwltool.
Basically, it reads CWL files, it writes CWL files from R flavored
pipeline description and it runs CWL tools.
Naive question: what does they gain?
CWL extended by R?

1- they describes the workflow with snakemake and so it is natively
extendable with Python; then the "graph" is exported to CWL file.
2- they imports a complete CWL workflow as a snakemake rule; then
this rule runs cwltool, and can be connected to any other snakemake
rules.

We already had a discussion about this idea on guix-devel, one year ago. :-)

I agree that a "CWL engine" would be nice. I mean my mind has not
changed so much since last year. ;-)
What is blocking to push your guix-cwl channel to Guix master?
All the best
