/**
* SYSEXITS.H -- Exit status codes for system programs.
*
* <P>Converted from a C header file to a Java Interface, for inclusion
* in SMTP software. The Interface defines a bunch of public static
* final int constants, but no methods, so it works much like a C-language
* #include with just #define'd numbers...
*
* <P>This include file attempts to categorize possible error
* exit statuses for system programs, notably delivermail
* and the Berkeley network.
*
* <P>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:
*
* <P>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.
* <P>EX_DATAERR -- The input data was incorrect in some way.
* This should only be used for user's data & not
* system files.
* <P>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).
* <P>EX_NOUSER -- The user specified did not exist. This might
* be used for mail addresses or remote logins.
* <P>EX_NOHOST -- The host specified did not exist. This is used
* in mail addresses or network requests.
* <P>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.
* <P>EX_SOFTWARE -- An internal software error has been detected.
* This should be limited to non-operating system related
* errors as much as possible.
* <P>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.
* <P>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).
* <P>EX_CANTCREAT -- A (user specified) output file cannot be
* created.
* <P>EX_IOERR -- An error occurred while doing IO on some file.
* <P>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.
* <P>EX_PROTOCOL -- the remote system returned something that
* was "not possible" during a protocol exchange.
* <P>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.
