the compression is nice to have of course but the uniqing is very neat. I have always though of it as plan9's answer to CSV et al. When you do a release of a software package you copy the files to a new directory with the name of the release (the equivilent of tagging your release in CVS) - and continue working. this tne takes up the space for the directory entries and all releases are always available. branching is trivial (dircp) only a pretty merge tool is missing - I have diff3 from edition7 in my contrib area but some sort of interactive differencting GUI tool would be very hand somtimes. have I drifted off topic I wonder... -Steve
