Yeah I understand. Out of curiosity where does it save the redists in Windows? When I was trying to get it to work, it always kept re-downloading them. Are there plans to make it cache the redists instead? To avoid unnecessary bandwidth usage? (Yeah I know few MBs, but there are people with heavily capped internet so all the savings is always better.)
I've been working on prereqs (redists) just yesterday and I was thinking the same thing. The test-prereqs command I just added to butler v6.0.0 does cache them, since I had to run it so often :)
Prerequisites are better documented as of yesterday btw: https://itch.io/docs/itch/integrating/prereqs/
