You commit to the trunk, then you do "svnmerge merge -r<rev>" in the 3k
branch, then "svn commit -F svnmerge-something.txt" (in case of
conflicts, you fix them first, of course).

I'm not sure - I think the install script must run several times
actually, so there must be several custom actions, each with its own
condition.

Well, if there had been separate packages per version, you could install
them independently, anyway.
