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 8 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, and a
just-in-time compiler that can be used to optimize pattern matching. These
are both optional features that can be omitted when the library is built.

Xpdf
====

version 3.03
2011-aug-15

The Xpdf software and documentation are
copyright 1996-2011 Glyph & Cog, LLC.

Email: derekn@foolabs.com
WWW: http://www.foolabs.com/xpdf/

The PDF data structures, operators, and specification are
copyright 1985-2006 Adobe Systems Inc.


What is Xpdf?
-------------

Xpdf is an open source viewer for Portable Document Format (PDF)
files.  (These are also sometimes also called 'Acrobat' files, from
the name of Adobe's PDF software.)  The Xpdf project also includes a
PDF text extractor, PDF-to-PostScript converter, and various other
utilities.

Xpdf runs under the X Window System on UNIX, VMS, and OS/2.  The non-X
components (pdftops, pdftotext, etc.) also run on Windows and Mac OSX
systems and should run on pretty much any system with a decent C++
compiler.  Xpdf will run on 32-bit and 64-bit machines.


License & Distribution
----------------------

Xpdf is licensed under the GNU General Pulbic License (GPL), version 2
or 3.  This means that you can distribute derivatives of Xpdf under
any of the following:
  - GPL v2 only
  - GPL v3 only
  - GPL v2 or v3

The Xpdf source package includes the text of both GPL versions:
COPYING for GPL v2, COPYING3 for GPL v3.

Please note that Xpdf is NOT licensed under "any later version" of the
GPL, as I have no idea what those versions will look like.

If you are redistributing unmodified copies of Xpdf (or any of the
Xpdf tools) in binary form, you need to include all of the
documentation: README, man pages (or help files), COPYING, and
COPYING3.

If you want to incorporate the Xpdf source code into another program
(or create a modified version of Xpdf), and you are distributing that
program, you have two options: release your program under the GPL (v2
and/or v3), or purchase a commercial Xpdf source license.

If you're interested in commercial licensing, please see the Glyph &
Cog web site:

[uchardet](https://github.com/BYVoid/uchardet) is a C language binding of the original C++
implementation of the universal charset detection library by Mozilla.

uchardet is an encoding detector library, which takes a sequence of bytes in an unknown character
encoding without any additional information, and attempts to determine the encoding of the text.

The original code of universalchardet is available at http://lxr.mozilla.org/seamonkey/source/extensions/universalchardet/

Techniques used by universalchardet are described at http://www.mozilla.org/projects/intl/UniversalCharsetDetection.html
