--- Comment #29 from Bamm Gabriana bammgabriana@gmail.com --- Interesting. It shouldn't be hard to recreate the logic into a Windows program, or to create an elf in winelib just to run the script. But doing that will mean it cannot be made into a separate package, As I understood it, this bug was closed precisely because they believe such a thing should be an external tool.
If I can just drop files in certain places that automagically causes the script to run at wineboot, it should be trivial to create a deb or rpm that people can install separately, if they desire this feature. I also prefer this so I can continue maintaining the script independent of Wine development.
