Okay, so what does all of this mean to me as 1) a packager and 2) an end-user? Nothing on the wiki yet. (I'll update the wiki but I haven't a clue what to write.)

Are we supposed to start building Trinity using QT4 rather than QT3?

Do we build for both QT3 and QT4 and whichever QT package the end-user has installed is the one Trinity will use?

If both QT3 and QT4 is installed which gets used by Trinity when the end-user runs Trinity?
