HEAD is obvious. But the others aren't, and I can't find a real listing anywhere. I'd like to use INGO, but I don't want the rest of my HORDE setup to be on the bleeding edge, so I don't want to use the HEAD release (which would require me changing to HORDE 3.0). What does the RELENG_1 tag mean? Is that compatible with Horde 2.x? jim
