itch-setup
This is the install and self-update helper for the itch.io app
It applies a few tricks it learned from Squirrel.Mac and Squirrel.Windows, and
uses some of the same technology behind butler, itch.io's command line
uploader and patcher.
What does it look like?
Something like this:
This is a screen you should only see the first time you launch the itch.io app,
or if your itch install gets corrupted on disk somehow.
Any upgrades happen seamlessly in the background.
