+**  SYSEXITS.H -- Exit status codes for system programs.
+**
+**	This include file attempts to categorize possible error
+**	exit statuses for system programs, notably delivermail
+**	and the Berkeley network.
+**
+**	Error numbers begin at EX__BASE to reduce the possibility of
+**	clashing with other exit statuses that random programs may
+**	already return.  The meaning of the codes is approximately
+**	as follows:
+**
+**	EX_USAGE -- The command was used incorrectly, e.g., with
+**		the wrong number of arguments, a bad flag, a bad
+**		syntax in a parameter, or whatever.
+**	EX_DATAERR -- The input data was incorrect in some way.
+**		This should only be used for user's data & not
+**		system files.
+**	EX_NOINPUT -- An input file (not a system file) did not
+**		exist or was not readable.  This could also include
+**		errors like "No message" to a mailer (if it cared
+**		to catch it).
+**	EX_NOUSER -- The user specified did not exist.  This might
+**		be used for mail addresses or remote logins.
+**	EX_NOHOST -- The host specified did not exist.  This is used
+**		in mail addresses or network requests.
+**	EX_UNAVAILABLE -- A service is unavailable.  This can occur
+**		if a support program or file does not exist.  This
+**		can also be used as a catchall message when something
+**		you wanted to do doesn't work, but you don't know
+**		why.
+**	EX_SOFTWARE -- An internal software error has been detected.
+**		This should be limited to non-operating system related
+**		errors as possible.
+**	EX_OSERR -- An operating system error has been detected.
+**		This is intended to be used for such things as "cannot
+**		fork", "cannot create pipe", or the like.  It includes
+**		things like getuid returning a user that does not
+**		exist in the passwd file.
+**	EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
+**		etc.) does not exist, cannot be opened, or has some
+**		sort of error (e.g., syntax error).
+**	EX_CANTCREAT -- A (user specified) output file cannot be
+**		created.
+**	EX_IOERR -- An error occurred while doing I/O on some file.
+**	EX_TEMPFAIL -- temporary failure, indicating something that
+**		is not really an error.  In sendmail, this means
+**		that a mailer (e.g.) could not create a connection,
+**		and the request should be reattempted later.
+**	EX_PROTOCOL -- the remote system returned something that
+**		was "not possible" during a protocol exchange.
+**	EX_NOPERM -- You did not have sufficient permission to
+**		perform the operation.  This is not intended for
+**		file system problems, which should use NOINPUT or
+**		CANTCREAT, but rather for higher level permissions.
