hi @richiardiandrea

I just used your snippet to create a classpath file

With a change made to Lumo (unpublished) and the most recent version of Mach, you can do: #addcp "cp"

this dynamically updates the Lumo classpath to use what's in the relative file classpath

another change to Mach has made it so adhoc requires work.

@jonpither awesome, I saw the commit on master and will try that out
