+///
+/// Win32 version of the AMD 3DNow! optimized routines for AMD K6-2/Athlon 
+/// processors. All 3DNow! optimized functions have been gathered into this
+/// single source code file, regardless to their class or original source code 
+/// file, in order to ease porting the library to other compiler and processor 
+/// platforms.
+///
+/// By the way; the performance gain depends heavily on the CPU generation: On 
+/// K6-2 these routines provided speed-up of even 2.4 times, while on Athlon the 
+/// difference to the original routines stayed at unremarkable 8%! Such a small 
+/// improvement on Athlon is due to 3DNow can perform only two operations in 
+/// parallel, and obviously also the Athlon FPU is doing a very good job with
+/// the standard C floating point routines! Here these routines are anyway, 
+/// although it might not be worth the effort to convert these to GCC platform, 
+/// for Athlon CPU at least. The situation is different regarding the SSE 
+/// optimizations though, thanks to the four parallel operations of SSE that 
+/// already make a difference.
+/// 
+/// This file is to be compiled in Windows platform with Microsoft Visual C++ 
+/// Compiler. Please see '3dnow_gcc.cpp' for the gcc compiler version for all
+/// GNU platforms (if file supplied).
+///
+/// NOTICE: If using Visual Studio 6.0, you'll need to install the "Visual C++ 
+/// 6.0 processor pack" update to support 3DNow! instruction set. The update is 
+/// available for download at Microsoft Developers Network, see here:
+/// http://msdn.microsoft.com/vstudio/downloads/tools/ppack/default.aspx
+///
+/// If the above URL is expired or removed, go to "http://msdn.microsoft.com" and

+///
+/// Beats-per-minute (BPM) detection routine.
+///
+/// The beat detection algorithm works as follows:
+/// - Use function 'inputSamples' to input a chunks of samples to the class for
+///   analysis. It's a good idea to enter a large sound file or stream in smallish
+///   chunks of around few kilosamples in order not to extinguish too much RAM memory.
+/// - Input sound data is decimated to approx 500 Hz to reduce calculation burden,
+///   which is basically ok as low (bass) frequencies mostly determine the beat rate.
+///   Simple averaging is used for anti-alias filtering because the resulting signal
+///   quality isn't of that high importance.
+/// - Decimated sound data is enveloped, i.e. the amplitude shape is detected by
+///   taking absolute value that's smoothed by sliding average. Signal levels that
+///   are below a couple of times the general RMS amplitude level are cut away to
+///   leave only notable peaks there.
+/// - Repeating sound patterns (e.g. beats) are detected by calculating short-term 
+///   autocorrelation function of the enveloped signal.
+/// - After whole sound data file has been analyzed as above, the bpm level is 
+///   detected by function 'getBpm' that finds the highest peak of the autocorrelation 
+///   function, calculates it's precise location and converts this reading to bpm's.

+/// SoundTouch - main class for tempo/pitch/rate adjusting routines. 
+///
+/// Notes:
+/// - Initialize the SoundTouch object instance by setting up the sound stream 
+///   parameters with functions 'setSampleRate' and 'setChannels', then set 
+///   desired tempo/pitch/rate settings with the corresponding functions.
+///
+/// - The SoundTouch class behaves like a first-in-first-out pipeline: The 
+///   samples that are to be processed are fed into one of the pipe by calling
+///   function 'putSamples', while the ready processed samples can be read 
+///   from the other end of the pipeline with function 'receiveSamples'.
+/// 
+/// - The SoundTouch processing classes require certain sized 'batches' of 
+///   samples in order to process the sound. For this reason the classes buffer 
+///   incoming samples until there are enough of samples available for 
+///   processing, then they carry out the processing step and consequently
+///   make the processed samples available for outputting.
+/// 
+/// - For the above reason, the processing routines introduce a certain 
+///   'latency' between the input and output, so that the samples input to
+///   SoundTouch may not be immediately available in the output, and neither 
+///   the amount of outputtable samples may not immediately be in direct 
+///   relationship with the amount of previously input samples.
+///
+/// - The tempo/pitch/rate control parameters can be altered during processing.
+///   Please notice though that they aren't currently protected by semaphores,
+///   so in multi-thread application external semaphore protection may be
+///   required.
+///
+/// - This class utilizes classes 'TDStretch' for tempo change (without modifying
+///   pitch) and 'RateTransposer' for changing the playback rate (that is, both 
+///   tempo and pitch in the same ratio) of the sound. The third available control 
+///   'pitch' (change pitch but maintain tempo) is produced by a combination of
+///   combining the two other controls.

+///
+/// SoundTouch - main class for tempo/pitch/rate adjusting routines. 
+///
+/// Notes:
+/// - Initialize the SoundTouch object instance by setting up the sound stream 
+///   parameters with functions 'setSampleRate' and 'setChannels', then set 
+///   desired tempo/pitch/rate settings with the corresponding functions.
+///
+/// - The SoundTouch class behaves like a first-in-first-out pipeline: The 
+///   samples that are to be processed are fed into one of the pipe by calling
+///   function 'putSamples', while the ready processed samples can be read 
+///   from the other end of the pipeline with function 'receiveSamples'.
+/// 
+/// - The SoundTouch processing classes require certain sized 'batches' of 
+///   samples in order to process the sound. For this reason the classes buffer 
+///   incoming samples until there are enough of samples available for 
+///   processing, then they carry out the processing step and consequently
+///   make the processed samples available for outputting.
+/// 
+/// - For the above reason, the processing routines introduce a certain 
+///   'latency' between the input and output, so that the samples input to
+///   SoundTouch may not be immediately available in the output, and neither 
+///   the amount of outputtable samples may not immediately be in direct 
+///   relationship with the amount of previously input samples.
+///
+/// - The tempo/pitch/rate control parameters can be altered during processing.
+///   Please notice though that they aren't currently protected by semaphores,
+///   so in multi-thread application external semaphore protection may be
+///   required.
+///
+/// - This class utilizes classes 'TDStretch' for tempo change (without modifying
+///   pitch) and 'RateTransposer' for changing the playback rate (that is, both 
+///   tempo and pitch in the same ratio) of the sound. The third available control 
+///   'pitch' (change pitch but maintain tempo) is produced by a combination of
+///   combining the two other controls.

+This is the README for bzip2/libzip2.
+This version is fully compatible with the previous public releases.
+
+------------------------------------------------------------------
+This file is part of bzip2/libbzip2, a program and library for
+lossless, block-sorting data compression.
+
+bzip2/libbzip2 version 1.0.4 of 20 December 2006
+Copyright (C) 1996-2006 Julian Seward <jseward@bzip.org>

+Complete documentation is available in Postscript form (manual.ps),
+PDF (manual.pdf) or html (manual.html).  A plain-text version of the
+manual page is available as bzip2.txt.
+
+
+HOW TO BUILD -- UNIX
+
+Type 'make'.  This builds the library libbz2.a and then the programs
+bzip2 and bzip2recover.  Six self-tests are run.  If the self-tests
+complete ok, carry on to installation:
+
+To install in /usr/local/bin, /usr/local/lib, /usr/local/man and
+/usr/local/include, type
+
+   make install
+
+To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type
+
+   make install PREFIX=/xxx/yyy
+
+If you are (justifiably) paranoid and want to see what 'make install'
+is going to do, you can first do
+
+   make -n install                      or
+   make -n install PREFIX=/xxx/yyy      respectively.
+
+The -n instructs make to show the commands it would execute, but not
+actually execute them.
+
+
+HOW TO BUILD -- UNIX, shared library libbz2.so.
+
+Do 'make -f Makefile-libbz2_so'.  This Makefile seems to work for
+Linux-ELF (RedHat 7.2 on an x86 box), with gcc.  I make no claims
+that it works for any other platform, though I suspect it probably
+will work for most platforms employing both ELF and gcc.
+
+bzip2-shared, a client of the shared library, is also built, but not
+self-tested.  So I suggest you also build using the normal Makefile,
+since that conducts a self-test.  A second reason to prefer the
+version statically linked to the library is that, on x86 platforms,
+building shared objects makes a valuable register (%ebx) unavailable
+to gcc, resulting in a slowdown of 10%-20%, at least for bzip2.
+
+Important note for people upgrading .so's from 0.9.0/0.9.5 to version
+1.0.X.  All the functions in the library have been renamed, from (eg)
+bzCompress to BZ2_bzCompress, to avoid namespace pollution.
+Unfortunately this means that the libbz2.so created by
+Makefile-libbz2_so will not work with any program which used an older
+version of the library.  I do encourage library clients to make the
+effort to upgrade to use version 1.0, since it is both faster and more
+robust than previous versions.
+
+
+HOW TO BUILD -- Windows 95, NT, DOS, Mac, etc.
+
+It's difficult for me to support compilation on all these platforms.
+My approach is to collect binaries for these platforms, and put them
+on the master web site (http://www.bzip.org).  Look there.  However
+(FWIW), bzip2-1.0.X is very standard ANSI C and should compile
+unmodified with MS Visual C.  If you have difficulties building, you
+might want to read README.COMPILATION.PROBLEMS.
+
+At least using MS Visual C++ 6, you can build from the unmodified
+sources by issuing, in a command shell: 
+
+   nmake -f makefile.msc
+
+(you may need to first run the MSVC-provided script VCVARS32.BAT
+ so as to set up paths to the MSVC tools correctly).
+
+
+VALIDATION
+
+Correct operation, in the sense that a compressed file can always be
+decompressed to reproduce the original, is obviously of paramount
+importance.  To validate bzip2, I used a modified version of Mark
+Nelson's churn program.  Churn is an automated test driver which
+recursively traverses a directory structure, using bzip2 to compress
+and then decompress each file it encounters, and checking that the
+decompressed data is the same as the original.
+
+
+
+Please read and be aware of the following:
+
+WARNING:
+
+   This program and library (attempts to) compress data by 
+   performing several non-trivial transformations on it.  
+   Unless you are 100% familiar with *all* the algorithms 
+   contained herein, and with the consequences of modifying them, 
+   you should NOT meddle with the compression or decompression 
+   machinery.  Incorrect changes can and very likely *will* 
+   lead to disastrous loss of data.
+
+
+DISCLAIMER:
+
+   I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
+   USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED.
+
+   Every compression of a file implies an assumption that the
+   compressed file can be decompressed to reproduce the original.
+   Great efforts in design, coding and testing have been made to
+   ensure that this program works correctly.  However, the complexity
+   of the algorithms, and, in particular, the presence of various
+   special cases in the code which occur with very low but non-zero
+   probability make it impossible to rule out the possibility of bugs
+   remaining in the program.  DO NOT COMPRESS ANY DATA WITH THIS
+   PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER
+   SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
+
+   That is not to say this program is inherently unreliable.  
+   Indeed, I very much hope the opposite is true.  bzip2/libbzip2 
+   has been carefully constructed and extensively tested.
+
+
+PATENTS:
+
+   To the best of my knowledge, bzip2/libbzip2 does not use any 
+   patented algorithms.  However, I do not have the resources 
+   to carry out a patent search.  Therefore I cannot give any 
+   guarantee of the above statement.
+
+
+
+WHAT'S NEW IN 0.9.0 (as compared to 0.1pl2) ?
+
+   * Approx 10% faster compression, 30% faster decompression
+   * -t (test mode) is a lot quicker
+   * Can decompress concatenated compressed files
+   * Programming interface, so programs can directly read/write .bz2 files
+   * Less restrictive (BSD-style) licensing
+   * Flag handling more compatible with GNU gzip
+   * Much more documentation, i.e., a proper user manual
+   * Hopefully, improved portability (at least of the library)
+
+WHAT'S NEW IN 0.9.5 ?
+
+   * Compression speed is much less sensitive to the input
+     data than in previous versions.  Specifically, the very
+     slow performance caused by repetitive data is fixed.
+   * Many small improvements in file and flag handling.
+   * A Y2K statement.
+
+WHAT'S NEW IN 1.0.0 ?

+         time, enough to verify that it works.

+         order to preserve backwards compatibility with bitstreams

+                ChangeLog file for zlib
+
+Changes in 1.2.3 (18 July 2005)
+- Apply security vulnerability fixes to contrib/infback9 as well
+- Clean up some text files (carriage returns, trailing space)
+- Update testzlib, vstudio, masmx64, and masmx86 in contrib [Vollant]
+
+Changes in 1.2.2.4 (11 July 2005)
+- Add inflatePrime() function for starting inflation at bit boundary
+- Avoid some Visual C warnings in deflate.c
+- Avoid more silly Visual C warnings in inflate.c and inftrees.c for 64-bit
+  compile
+- Fix some spelling errors in comments [Betts]
+- Correct inflateInit2() error return documentation in zlib.h
+- Added zran.c example of compressed data random access to examples
+  directory, shows use of inflatePrime()
+- Fix cast for assignments to strm->state in inflate.c and infback.c
+- Fix zlibCompileFlags() in zutil.c to use 1L for long shifts [Oberhumer]
+- Move declarations of gf2 functions to right place in crc32.c [Oberhumer]
+- Add cast in trees.c t avoid a warning [Oberhumer]
+- Avoid some warnings in fitblk.c, gun.c, gzjoin.c in examples [Oberhumer]
+- Update make_vms.com [Zinser]
+- Initialize state->write in inflateReset() since copied in inflate_fast()
+- Be more strict on incomplete code sets in inflate_table() and increase
+  ENOUGH and MAXD -- this repairs a possible security vulnerability for
+  invalid inflate input.  Thanks to Tavis Ormandy and Markus Oberhumer for
+  discovering the vulnerability and providing test cases.
+- Add ia64 support to configure for HP-UX [Smith]

+- Remove trailing space in minigzip.c outmode (VC++ can't deal with it)
+- Fix crc check bug in gzread() after gzungetc() [Heiner]
+- Add the deflateTune() function to adjust internal compression parameters
+- Add a fast gzip decompressor, gun.c, to examples (use of inflateBack)
+- Remove an incorrect assertion in examples/zpipe.c
+- Add C++ wrapper in infback9.h [Donais]
+- Fix bug in inflateCopy() when decoding fixed codes
+- Note in zlib.h how much deflateSetDictionary() actually uses
+- Remove USE_DICT_HEAD in deflate.c (would mess up inflate if used)

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.3 is a general purpose data compression library.  All the code is
+thread safe.  The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format). These documents are also available in other
+formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
+of the library is given in the file example.c which also tests that the library
+is working correctly. Another example is given in the file minigzip.c. The
+compression library itself is composed of all source files except example.c and
+minigzip.c.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile. In short "make test; make install" should work for most
+machines. For Unix: "./configure; make test; make install". For MSDOS, use one
+of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version. The zlib home page is
+http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem,
+please check this site to verify that you have the latest version of zlib;
+otherwise get the latest version and check whether the problem still exists or
+not.
+
+PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
+for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
+issue of  Dr. Dobb's Journal; a copy of the article is available in
+http://dogma.net/markn/articles/zlibtool/zlibtool.htm
+
+The changes made in version 1.2.3 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory "contrib".
+
+A Java implementation of zlib is available in the Java Development Kit
+http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
+See the zlib home page http://www.zlib.org for details.
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
+CPAN (Comprehensive Perl Archive Network) sites
+http://www.cpan.org/modules/by-module/Compress/
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://www.python.org/doc/lib/module-zlib.html
+
+A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
+availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+  compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+  when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+  necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+  other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/
+
+- When building a shared, i.e. dynamic library on Mac OS X, the library must be
+  installed before testing (do "make install" before "make test"), since the
+  library location is specified in the library.
+
+
+Acknowledgments:
+
+  The deflate format used by zlib was defined by Phil Katz. The deflate
+  and zlib specifications were written by L. Peter Deutsch. Thanks to all the
+  people who reported problems and suggested various improvements in zlib;
+  they are too numerous to cite here.

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+   strm provides the memory allocation functions and window buffer on input,

+   returns, strm will also provide an error message.
+
+   in() and out() are the call-back input and output functions.  When
+   inflateBack() needs more input, it calls in().  When inflateBack() has
+   filled the window with output, or when it completes with data in the
+   window, it calls out() to write out the data.  The application must not
+   change the provided input until in() is called again or inflateBack()
+   returns.  The application must not change the window/output buffer until
+   inflateBack() returns.
+
+   in() and out() are called with a descriptor parameter provided in the
+   inflateBack() call.  This parameter can be a structure that provides the
+   information required to do the read or write, as well as accumulated
+   information on the input and output such as totals and check values.
+
+   in() should return zero on failure.  out() should return non-zero on
+   failure.  If either in() or out() fails, than inflateBack() returns a
+   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
+   was in() or out() that caused in the error.  Otherwise,  inflateBack()
+   returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+   error, or Z_MEM_ERROR if it could not allocate memory for the state.
+   inflateBack() can also return Z_STREAM_ERROR if the input parameters
+   are not correct, i.e. strm is Z_NULL or the state was not initialized.

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
