Batch files for running multiple DMD versions?

[Burton Radons]

Does anyone have a batch file setup for running multiple DMD versions, that 
works with 2.025's refit? Specifically I want DMD 1.0, DMD 2.0, Tango, and 
Other, that can be run to install new versions when they're released and allow 
me to run "dmd-2.0" or "bud-tango" and it'll just work. I'm like 70% done 
already but I thought I'd use someone else's wheel for once, if it exists.
