Specifically, here’s how I would launch Cuirass for testing purposes:

This example instructs Cuirass to populate the ‘cuirass.db’ file from
the current directory, to check the repo in the current directory every
10 seconds, and to use the job specification from ‘examples/random.scm’.
The HTTP server of Cuirass is listening on ‘localhost’, port 8080.

Let me know if you have any questions!  (I’m civodul on #guile.)

HTH,
Ludo’.
