+;;; KA9Q is not really an OS, but an ftp server that runs on PC's.
+;;; It runs under DOS and unix. Seems to have been adopted by LINUX.
+;; KA9Q uses unix syntax for paths, so don't need to bother with pathname
+;; converters. It always gives a listing, even if a file or dir doesn't
+;; exist. Therefore, we shall assume that empty dir = nonexistent dir. sigh...
