It was taken from Bionic libc, used on Android. 133 134The implementation of DES for crypt (src/crypt/crypt_des.c) is 135Copyright © 1994 David Burren. It is licensed under a BSD license. 136 137The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was 138originally written by Solar Designer and placed into the public 139domain. The code also comes with a fallback permissive license for use 140in jurisdictions that may not recognize the public domain. 141 142The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011 143Valentin Ochs and is licensed under an MIT-style license. 144 145The x86_64 port was written by Nicholas J. Kain and is licensed under 146the standard MIT terms. 147 148The mips and microblaze ports were originally written by Richard 149Pennington for use in the ellcc project. The original code was adapted 150by Rich Felker for build system and code conventions during upstream 151integration. It is licensed under the standard MIT terms. 152 153The mips64 port was contributed by Imagination Technologies and is 154licensed under the standard MIT terms. 155 156The powerpc port was also originally written by Richard Pennington, 157and later supplemented and integrated by John Spencer. It is licensed 158under the standard MIT terms. 159 160All other files which have no copyright comments are original works 161produced specifically for use as part of this library, written either 162by Rich Felker, the main author of the library, or by one or more 163contibutors listed above. Details on authorship of individual files 164can be found in the git version control history of the project. The 165omission of copyright and license comments in each file is in the 166interest of source tree size. 167 168In addition, permission is hereby granted for all public header files 169(include/* and arch/*/bits/*) and crt files intended to be linked into 170applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit 171the copyright notice and permission notice otherwise required by the 172license, and to use these files without any requirement of 173attribution.

In the spirit of 189permissive licensing, and of not having licensing issues being an 190obstacle to adoption, that text has been removed. 191
