As opposed to Un*x systems, Macs don't really communicate with the OS with
POSIXish calls, so POSIX libraries are always user level code. MacPerl links
with GUSI, a POSIXish library I did myself. That means that for all OS calls
taking path names, the parsing of the names is under my control, and I've taken
the liberty of assigning special meanings to some of the names (to the chagrin
of a few people who are using Dev: as a real disk name).

Johns list is complete, as far as I remember.
