1PCRE2 LICENCE 2------------- 3 4PCRE2 is a library of functions to support regular expressions whose syntax 5and semantics are as close as possible to those of the Perl 5 language. 6 7Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD" 8licence, as specified below, with one exemption for certain binary 9redistributions. The documentation for PCRE2, supplied in the "doc" directory, 10is distributed under the same terms as the software itself. The data in the 11testdata directory is not copyrighted and is in the public domain. 12 13The basic library functions are written in C and are freestanding. Also 14included in the distribution is a just-in-time compiler that can be used to 15optimize pattern matching. This is an optional feature that can be omitted when 16the library is built. 17 18 19THE BASIC LIBRARY FUNCTIONS 20--------------------------- 21 22Written by: Philip Hazel 23Email local part: Philip.Hazel 24Email domain: gmail.com 25 26University of Cambridge Computing Service, 27Cambridge, England. 28 29Copyright (c) 1997-2020 University of Cambridge 30All rights reserved. 31 32 33PCRE2 JUST-IN-TIME COMPILATION SUPPORT 34-------------------------------------- 35 36Written by: Zoltan Herczeg 37Email local part: hzmester 38Email domain: freemail.hu 39 40Copyright(c) 2010-2020 Zoltan Herczeg 41All rights reserved. 42 43 44STACK-LESS JUST-IN-TIME COMPILER 45-------------------------------- 46 47Written by: Zoltan Herczeg 48Email local part: hzmester 49Email domain: freemail.hu 50 51Copyright(c) 2009-2020 Zoltan Herczeg 52All rights reserved. 53 54 55THE "BSD" LICENCE 56----------------- 57 58Redistribution and use in source and binary forms, with or without 59modification, are permitted provided that the following conditions are met: 60 61 * Redistributions of source code must retain the above copyright notices, 62 this list of conditions and the following disclaimer. 63 64 * Redistributions in binary form must reproduce the above copyright 65 notices, this list of conditions and the following disclaimer in the 66 documentation and/or other materials provided with the distribution. 67 68 * Neither the name of the University of Cambridge nor the names of any 69 contributors may be used to endorse or promote products derived from this 70 software without specific prior written permission. 71 72THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" 73AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE 74IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE 75ARE DISCLAIMED.
