65 * Take a look around to catch any fatal errors. For example, make sure the
66 * destination directory for our working files exists, check that all
67 * pathnames make sense, and so on. Returns 0 is everything's ok,
68 # -1 if there's something wrong which will keep us from functioning
71 * We do all these checks at startup so we can print a reasonable error
72 * message on stderr before we disassociate from the controlling tty. This
73 * keeps some fatal error messages from "disappearing" into syslog.
