+* 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.

+and labelled as such. All have been licensed under extremely
+permissive terms. See the comments in the individual files for
+details.
+
+The implementation of DES for crypt (src/misc/crypt_des.c) is
+Copyright © 1994 David Burren. It is licensed under a BSD license.
+
+The implementation of blowfish crypt (src/misc/crypt_blowfish.c) was
+originally written by Solar Designer and placed into the public
+domain. The code also comes with a fallback permissive license for use
+in jurisdictions that may not recognize the public domain.
+
+The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
+Valentin Ochs and is licensed under an MIT-style license.
+
+The BSD PRNG implementation (src/prng/random.c) and XSI search API
+(src/search/*.c) functions are Copyright © 2011 Szabolcs Nagy and
+licensed under following terms: "Permission to use, copy, modify,
+and/or distribute this code for any purpose with or without fee is
+hereby granted. There is no warranty."
+
+The x86_64 port was written by Nicholas J. Kain. Several files (crt)
+were released into the public domain; others are licensed under the
+standard MIT license terms at the top of this file. See individual
+files for their copyright status.
+
+The mips and microblaze ports were originally written by Richard
+Pennington for use in the ellcc project. The original code was adapted
+by Rich Felker for build system and code conventions during upstream
+integration. It is licensed under the standard MIT terms.
+
+The powerpc port was also originally written by Richard Pennington,
+and later supplemented and integrated by John Spencer. It is licensed
+under the standard MIT terms.
+
+All other files which have no copyright comments are original works
+Copyright © 2005-2012 Rich Felker, the main author of this library.
+The decision to exclude such comments is intentional, as it should be
+possible to carry around the complete source code on tiny storage
+media. All public header files (include/*) should be treated as Public
+Domain as they intentionally contain no content which can be covered
+by copyright. Some source modules may fall in this category as well.
+If you believe that a file is so trivial that it should be in the
+Public Domain, please contact me and, if I agree, I will explicitly
+release it from copyright.

+The following files are trivial, in my opinion not copyrightable in
+the first place, and hereby explicitly released to the Public Domain:
