A work-in-progress command, "brew which" will show which versions of formulae you have installed based on what symlinks exist from HOMEBREW_PREFIX back into the Cellar. Thus, if you happen to have symlinks into two different versions of a brew in the Cellar (typically an error), both of those versions will be listed. This is a diagnostic command, but some of this code will be the basis for possible future better handling of multiple-versions-at-once.
