OK, I've been doing bug triage on and off for years, but just recently I've gotten to the point where I'm tired of going to the NativeDCOM wiki page to remember how to try an app with native dcom just to see if the bug in question is a COM bug.
So I wrote a trivial script to automate installing that plus a bunch of other redistributables. A draft is at http://kegel.com/wine/winetricks

It's a bit like a programmer's version of winetools: it's so commandline-crufty that normal users won't go near it, but it's simple enough to extend that it will probably end up being pretty handy for anyone working on triaging bugs that appear to be due to missing redistributable libraries. Oh, or commonly-needed registry entries. - Dan
