-The Android Open Source Project and is licensed under a two-clause BSD
-license. It was taken from Bionic libc, used on Android.
-
-The implementation of DES for crypt (src/crypt/crypt_des.c) is
-Copyright © 1994 David Burren. It is licensed under a BSD license.
-
-The implementation of blowfish crypt (src/crypt/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,

-hereby granted. There is no warranty."
-
-The x86_64 port was written by Nicholas J. Kain and is licensed under
-the standard MIT terms.
-
-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 mips64 port was contributed by Imagination Technologies and 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
-produced specifically for use as part of this library, written either
-by Rich Felker, the main author of the library, or by one or more
-contibutors listed above. Details on authorship of individual files
-can be found in the git version control history of the project. The
-omission of copyright and license comments in each file is in the

-all of whom have explicitly granted such permission.
-
-This file previously contained text expressing a belief that most of
-the files covered by the above exception were sufficiently trivial not
-to be subject to copyright, resulting in confusion over whether it
-negated the permissions granted in the license. In the spirit of
-permissive licensing, and of not having licensing issues being an
-obstacle to adoption, that text has been removed.
