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