Hello,
While writting the games compatibility list, i wanted to use a different fake_windows with every game. It was a bit bored, make the fake_windows and prepare the config files everytime. So i wrote a simple perl script what helps doing it.
If you are interested in use it, uncompress the wineenv.tgz file in your home directory. Then edit the file wineenv.pl, modifing the vars regedit path, winedefault.reg path, and fake_windows base path. After edit the config file included in ".wineenv/config", with the info about your drives and your favourite options (it will be the default config), and finally rename your original ".wine" directory.
It is very easy to use. Run "wineenv.pl name-of-environment", and the first time what you run it, it will create the fake_windows, and the config files for this fake_windows, and besides this fake_windows will be the active (it does a link from .wine to .wineenv/name-of-environment). The next times what you use "wineenv.pl name-of-environment" with the same "name-of-environment", it will do that "name-of-environment" the active one.
