PCRE LICENCE
------------
PCRE is a library of functions to support regular expressions whose syntax
and semantics are as close as possible to those of the Perl 5 language.
Release 7 of PCRE is distributed under the terms of the "BSD" licence, as
specified below. The documentation for PCRE, supplied in the "doc"
directory, is distributed under the same terms as the software itself.
The basic library functions are written in C and are freestanding. Also
included in the distribution is a set of C++ wrapper functions.

/* NOTES FOR FUTURE MAINTAINERS: Do not use numbers with leading zeros, because
they may be treated as octal constants. The PCRE_PRERELEASE feature is for
identifying release candidates. It might be defined as -RC2, for example. In
real releases, it should be defined empty. Do not change the alignment of these
statments. The code in ./configure greps out the version numbers by using "cut"
to get values from column 29 onwards. These are substituted into pcre-config
and libpcre.pc. The values are not put into configure.ac and substituted here
(which would simplify this issue) because that makes life harder for those who
cannot run ./configure. As it now stands, this file need not be edited in that
circumstance. */

/* This file is automatically written by the dftables auxiliary
program. If you edit it by hand, you might like to edit the Makefile to
prevent its ever being regenerated.
/* This file contains character tables that are used when no external tables
are passed to PCRE by the application that calls it. The tables are used only
for characters whose code values are less than 256.
This file contains the default tables for characters with codes less than
128 (ASCII characters). These tables are used when no external tables are
passed to PCRE.
This is a default version of the tables that assumes ASCII encoding. A program
called dftables (which is distributed with PCRE) can be used to build
alternative versions of this file. This is necessary if you are running in an
EBCDIC environment, or if you want to default to a different encoding, for
example ISO-8859-1. When dftables is run, it creates these tables in the
current locale. If PCRE is configured with --enable-rebuild-chartables, this
happens automatically.
The following #include is present because without it gcc 4.x may remove
the array definition from the final binary if PCRE is built into a static
library and dead code stripping is activated. This leads to link errors.
Pulling in the header ensures that the array gets flagged as "someone
outside this compilation unit might reference this" and so it will always
be supplied to the linker. */

#define PCRE_DEFINITION /* Win32 __declspec(export) trigger for .dll */
/* When compiling a DLL for Windows, the exported symbols have to be declared
using some MS magic. I found some useful information on this web page:
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
information there, using __declspec(dllexport) without "extern" we have a
definition; with "extern" we have a declaration. The settings here override the
setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
which is all that is needed for applications (they just import the symbols). We
use:
PCRE_EXP_DECL for declarations
PCRE_EXP_DEFN for definitions of exported functions
PCRE_EXP_DATA_DEFN for definitions of exported variables
The reason for the two DEFN macros is that in non-Windows environments, one
does not want to have "extern" before variable definitions because it leads to
compiler warnings. So we distinguish between functions and variables. In
Windows, the two should always be the same.
The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
which is an application, but needs to import this file in order to "peek" at
internals, can #include pcre.h first to get an application's-eye view.
In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
special-purpose environments) might want to stick other stuff in front of
exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
PCRE_EXP_DATA_DEFN only if they are not already set. */

one kind of newline is to be recognized. When a newline is found, its length is
returned. In principle, we could implement several newline "types", each
referring to a different set of newline characters. At present, PCRE supports
only NLTYPE_FIXED, which gets handled without these functions, and NLTYPE_ALL,
so for now the type isn't passed into the functions. It can easily be added
later if required. The full list of Unicode newline characters is taken from
only NLTYPE_FIXED, which gets handled without these functions, NLTYPE_ANYCRLF,
and NLTYPE_ANY. The full list of Unicode newline characters is taken from
