Better docs please / FUBARed Arkham Asylum about protontricks HOT 1 OPEN

Protontricks is simply a wrapper for Winetricks. Winetricks does most of the heavy lifting here if you're just running Winetricks verbs. calibri, d3dx9 and d3dcompiler_43 in your reply are Winetricks verbs.

Winetricks does not generally allow you to uninstall anything; the recommended method is to delete the prefix entirely.

If you're using an installation method other than the Flatpak one (where running commands other than protontricks is a bit more involved), you can use winetricks --help to see what Winetricks commands are available. For any Winetricks command, instead of running winetricks FOO BAR, you run protontricks <APPID> FOO BAR.

Aside from that, the GitHub project page doesn't link directly to other documentation but there's the GitHub wiki and the article on WineHQ wiki.

Making the Winetricks commands discoverable outside the GUI could be improved, though I'm not sure what would be the best way to achieve this.
