It often happens (at least for me!) that in order to do a build I must check out an svn tree, say,

/trunk/myapp

but I don't want to actually trigger the build unless certain subsets of that tree have changed, e.g.

/trunk/myapp/dir1
/trunk/myapp/library/dira
/trunk/myapp/library/dirb

I would like to have a feature analogous to excludedRegions where I could specify these paths as includedRegions and the build would only be triggered if a checkin occurred that modified something in the includedRegions.

If both excludedRegions and includedRegions were specified, it would work in the obvious way, i.e. a change would have to have at least one path that was in includedRegions, but not in excludedRegions.
