I am pleased to announce the release of ccwl 0.5.0!

ccwl is a compiler to generate CWL workflows from concise descriptions  
in Scheme. It is implemented in Guile. You can see plenty of examples of  
ccwl workflows in the [manual](https://ccwl.systemreboot.net/manual/dev/en/).

ccwl is packaged for Guix. If you are on a recent enough Guix, you can  
drop into a shell with `guix shell ccwl’. You can try it out using the Docker and Singularity images provided on the GitHub releases page.

Patches and feedback welcome!
