A port of src/bin/uuidgen from FreeBSD to OpenBSD. The FreeBSD version relies on a call to uuidgen(2) in libc, which isn't in OpenBSD. I re-implemented this in the application itself (as void genuuid) vice in libc, since I'm not particularly keen to poke around in there. Source is attached below, and should also be available via cvs:
