So just tell me who's coordinating this stuff and I jump on the bandwagon. A propos, I will accomplish this not as an employee of SARA, but privately; that is: it's hard not to use 6 years of experience in operating system internals (CDC, DEC VMS (4 years) and UNICOS (few months)) but I won't COPY anything. > -- > Melinda Shore shore@mtxinu.com > mt Xinu ..!uunet!mtxinu.com!shore -- Toon Moene, SARA - Amsterdam (NL) Internet: TOON@SARA.NL Cyclists don't need a garage to start with.
