GNU has the fileutils (rm, ls, and so on) plus bash plus awk plus grep plus emacs; I use RCS so I don't need SCCS (RCS is roughly PD); all my network utilities and libraries are from Berkeley. I guess we've got some work on libc, but I think there's already a free libm. Just what things do you want that you can't already get from !ATT ? -- Paul Vixie DEC Western Research Lab Palo Alto, California ...!decwrl!vixie
