How do I find out if I am running native pure wine

[freiwitz]

I know that you can use --version to print the version but how do I verify that my wine working directory is pure and does not include winetricks additions, ms fonts etc.? Is there a script or command?

Overrides added by winetricks (or manually) will show up in winecfg, but added fonts and changes to registry settings won't.

The way to be sure a wineprefix is clean is to create a fresh one.
