PCRE LICENCE&#xA;------------&#xA;&#xA;PCRE is a library of functions to support regular expressions whose syntax&#xA;and semantics are as close as possible to those of the Perl 5 language.&#xA;&#xA;Release 8 of PCRE is distributed under the terms of the &#34;BSD&#34; licence, as&#xA;specified below. The documentation for PCRE, supplied in the &#34;doc&#34;&#xA;directory, is distributed under the same terms as the software itself.&#xA;&#xA;The basic library functions are written in C and are freestanding. Also&#xA;included in the distribution is a set of C++ wrapper functions, and a&#xA;just-in-time compiler that can be used to optimize pattern matching. These&#xA;are both optional features that can be omitted when the library is built.&#xA;&#xA;&#xA;THE BASIC LIBRARY FUNCTIONS&#xA;---------------------------&#xA;&#xA;Written by:       Philip Hazel&#xA;Email local part: ph10&#xA;Email domain:     cam.ac.uk&#xA;&#xA;University of Cambridge Computing Service,&#xA;Cambridge, England.&#xA;&#xA;Copyright (c) 1997-2014 University of Cambridge&#xA;All rights reserved.&#xA;&#xA;&#xA;PCRE JUST-IN-TIME COMPILATION SUPPORT&#xA;-------------------------------------&#xA;&#xA;Written by:       Zoltan Herczeg&#xA;Email local part: hzmester&#xA;Emain domain:     freemail.hu&#xA;&#xA;Copyright(c) 2010-2014 Zoltan Herczeg&#xA;All rights reserved.&#xA;&#xA;&#xA;STACK-LESS JUST-IN-TIME COMPILER&#xA;--------------------------------&#xA;&#xA;Written by:       Zoltan Herczeg&#xA;Email local part: hzmester&#xA;Emain domain:     freemail.hu&#xA;&#xA;Copyright(c) 2009-2014 Zoltan Herczeg&#xA;All rights reserved.&#xA;&#xA;&#xA;THE C++ WRAPPER FUNCTIONS&#xA;-------------------------&#xA;&#xA;Contributed by:   Google Inc.&#xA;&#xA;Copyright (c) 2007-2012, Google Inc.&#xA;All rights reserved.&#xA;&#xA;&#xA;THE &#34;BSD&#34; LICENCE&#xA;-----------------&#xA;&#xA;Redistribution and use in source and binary forms, with or without&#xA;modification, are permitted provided that the following conditions are met:&#xA;&#xA;    * Redistributions of source code must retain the above copyright notice,&#xA;      this list of conditions and the following disclaimer.&#xA;&#xA;    * Redistributions in binary form must reproduce the above copyright&#xA;      notice, this list of conditions and the following disclaimer in the&#xA;      documentation and/or other materials provided with the distribution.&#xA;&#xA;    * Neither the name of the University of Cambridge nor the name of Google&#xA;      Inc. nor the names of their contributors may be used to endorse or&#xA;      promote products derived from this software without specific prior&#xA;      written permission.&#xA;&#xA;THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS &#34;AS IS&#34;&#xA;AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE&#xA;IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE&#xA;ARE DISCLAIMED.
