	The mail spool directory back in the Version VII and, if I'm not
mistaken System III, days *was* in /usr/spool/mail. Since at least System V
it's been in /usr/mail, and *still is* for ISC UNIX and, if I'm not mistaken,
AT&T UNIX 386.

	Both SCO Xenix and SCO UNIX have *always* used /usr/spool/mail.
Sun and many BSD-based systems have followed that same convention. Perhaps
once Intel, ATT, ISC and SCO get together on the next UNIX 386 binary
standard they will clear up these and other subtle differences.
