A quick shell script for wine prefixes

Wine, the Windows emulator-that’s-not-an-emulator for Linux distributions, has a way of maintaining separate Windows systems using the WINEPREFIX and WINEARCH environment variables. While it’s a powerful mechanism, it’s not so handy to type it all in on the command line over and over. To that end, I have whipped up a simple shell script that handles most of that nasty business for you.
