1 PCRE2 LICENCE 2 ------------- 3 4 PCRE2 is a library of functions to support regular expressions whose syntax 5 and semantics are as close as possible to those of the Perl 5 language. 6 7 Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD" 8 licence, as specified below, with one exemption for certain binary 9 redistributions. The documentation for PCRE2, supplied in the "doc" directory, 10 is distributed under the same terms as the software itself. The data in the 11 testdata directory is not copyrighted and is in the public domain. 12 13 The basic library functions are written in C and are freestanding. Also 14 included in the distribution is a just-in-time compiler that can be used to 15 optimize pattern matching. This is an optional feature that can be omitted when 16 the library is built. 17 18 19 THE BASIC LIBRARY FUNCTIONS 20 --------------------------- 21 22 Written by: Philip Hazel 23 Email local part: ph10 24 Email domain: cam.ac.uk 25 26 University of Cambridge Computing Service, 27 Cambridge, England. 28 29 Copyright (c) 1997-2018 University of Cambridge 30 All rights reserved. 31 32 33 PCRE2 JUST-IN-TIME COMPILATION SUPPORT 34 -------------------------------------- 35 36 Written by: Zoltan Herczeg 37 Email local part: hzmester 38 Email domain: freemail.hu 39 40 Copyright(c) 2010-2018 Zoltan Herczeg 41 All rights reserved. 42 43 44 STACK-LESS JUST-IN-TIME COMPILER 45 -------------------------------- 46 47 Written by: Zoltan Herczeg 48 Email local part: hzmester 49 Email domain: freemail.hu 50 51 Copyright(c) 2009-2018 Zoltan Herczeg 52 All rights reserved. 53 54 55 THE "BSD" LICENCE 56 ----------------- 57 58 Redistribution and use in source and binary forms, with or without 59 modification, 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 72 THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" 73 AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE 74 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE 75 ARE DISCLAIMED.

If binary package A includes 90 PCRE2, it must respect the condition, but if package B is software that 91 includes package A, the condition is not imposed on package B unless it uses 92 PCRE2 independently. 93 94 End 95
