+/// 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/en-us/vstudio/aa718349.aspx

+/// 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.
+/// - Inputted 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.

+/// 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.

+<h2>1. Introduction </h2>
+<p>SoundTouch is an open-source audio processing library that allows
+changing the sound tempo, pitch and playback rate parameters
+independently from each other, i.e.:</p>
+<ul>
+  <li> Sound tempo can be increased or decreased while maintaining the
+original pitch </li>
+  <li> Sound pitch can be increased or decreased while maintaining the
+original tempo </li>
+  <li> Change playback rate that affects both tempo and pitch at the
+same time </li>
+  <li> Choose any combination of tempo/pitch/rate</li>
+</ul>

+<h2>2. Compiling SoundTouch</h2>
+<p>Before compiling, notice that you can choose the sample data format
+if it's desirable to use floating point sample data instead of 16bit
+integers. See section "sample data format" for more information.</p>
+<h3>2.1. Building in Microsoft Windows</h3>
+<p>Project files for Microsoft Visual C++ 6.0 and Visual C++ .NET are
+supplied with the source code package.<br>
+</p>
+<p> Please notice that SoundTouch library uses processor-specific
+optimizations for Pentium III and AMD processors. Visual Studio .NET
+and later versions supports the required instructions by default, but
+Visual Studio 6.0 requires a processor pack upgrade to be installed in
+order to support these optimizations. The processor pack upgrade can be
+downloaded from Microsoft site at this URL:</p>
+<p><a href="http://msdn.microsoft.com/en-us/vstudio/aa718349.aspx">http://msdn.microsoft.com/en-us/vstudio/aa718349.aspx</a></p>
+<p>If the above URL is unavailable or removed, go to <a
+ href="http://msdn.microsoft.com/"> http://msdn.microsoft.com</a> and
+perform a search with keywords "processor pack". </p>
+<p>To build the binaries with Visual C++ compiler, either run
+"make-win.bat" script, or open the appropriate project files in source
+code directories with Visual Studio. The final executable will appear
+under the "SoundTouch\bin" directory. If using the Visual Studio IDE
+instead of the make-win.bat script, directories bin and lib may need to
+be created manually to the SoundTouch package root for the final
+executables. The make-win.bat script creates these directories
+automatically. </p>
+<h3>2.2. Building in Gnu platforms</h3>
+<p>The SoundTouch library compiles in practically any platform
+supporting GNU compiler (GCC) tools. SoundTouch requires GCC version 4.3 or later.</p>
+<p>To build and install the binaries, run the following commands in 
+/soundtouch directory:</p>

+<h4><b>2.2.1 Required GNU tools</b>&nbsp;</h4>
+<p> <span style="font-weight: bold;">Bash shell</span>, <span
+ style="font-weight: bold;">GNU C++ compiler</span>, <span
+ style="font-weight: bold;">libtool</span>, <span
+ style="font-weight: bold;">autoconf</span> and <span
+ style="font-weight: bold;">automake</span> tools
+are required for compiling the SoundTouch library. These are usually
+included with the GNU/Linux distribution, but if not, install these
+packages first. For example, Ubuntu Linux can acquire and install
+these with the following command:</p>
+<pre><b>sudo apt-get install automake autoconf libtool build-essential</b></pre>
+<h4><b>2.2.2 Problems with GCC compiler compatibility</b></h4>
+<p>At the release time the SoundTouch package has been tested to
+compile in GNU/Linux platform. However, If you have problems getting the
+SoundTouch library compiled, try disabling optimizations that are specific for 
+x86 processors by running <b>./configure</b> script with switch
+<blockquote>
+<pre>--enable-x86-optimizations=no</pre>
+</blockquote>
+
+Alternatively, if you don't use GNU Configure system, edit file "include/STTypes.h" 
+directly and remove the following definition:<blockquote>
+  <pre>#define SOUNDTOUCH_ALLOW_X86_OPTIMIZATIONS 1</pre>
+</blockquote>
+
+<h4><b>2.2.3 Compiling Shared Library / DLL version</b></h4>
+    <p>
+        The GNU compilation does not automatically create a shared-library version of 
+        SoundTouch (.so or .dll). If such is desired, then you can create it as follows 
+        after running the usual compilation:</p>
+    <blockquote>
+  <pre>g++ -shared -static -DDLL_EXPORTS -I../../include -o SoundTouch.dll \
+     SoundTouchDLL.cpp ../SoundTouch/.libs/libSoundTouch.a
+sstrip SoundTouch.dll</pre>
+</blockquote>
+
+<h3>2.1. Building in Android</h3>
+<p>Android compilation instructions are within the 
+    source code package, see file &quot;<b>source/Android-lib/README-SoundTouch-Android.html</b>&quot; 
+    in the package.</p>
+
+<hr>
+<h2>3. About implementation &amp; Usage tips <h3>3.1. Supported sample data formats</h3>
+<p>The sample data format can be chosen between 16bit signed integer
+and 32bit floating point values, the default is 32bit floating point. </p>
+<p> In Windows environment, the sample data format is chosen in file
+"STTypes.h" by choosing one of the following defines:</p>
+<ul>
+  <li> <span style="font-weight: bold;">#define
+SOUNDTOUCH_INTEGER_SAMPLES</span> for 16bit signed integer </li>
+  <li> <span style="font-weight: bold;">#define </span><span
+ style="font-weight: bold;">SOUNDTOUCH_</span><span
+ style="font-weight: bold;">FLOAT_SAMPLES</span> for 32bit floating
+point</li>
+</ul>
+<p> In GNU environment, the floating sample format is used by default,
+but integer sample format can be chosen by giving the following switch
+to the configure script: </p>
+<blockquote>
+  <pre>./configure --enable-integer-samples</pre>
+</blockquote>
+<p>The sample data can have either single (mono) or double (stereo)
+audio channel. Stereo data is interleaved so that every other data
+value is for left channel and every second for right channel. Notice
+that while it'd be possible in theory to process stereo sound as two
+separate mono channels, this isn't recommended because processing the
+channels separately would result in losing the phase coherency between
+the channels, which consequently would ruin the stereo effect.</p>
+<p>Sample rates between 8000-48000H are supported.</p>
+<h3>3.2. Processing latency</h3>
+<p>The processing and latency constraints of the SoundTouch library are:</p>
+<ul>
+  <li> Input/output processing latency for the SoundTouch processor is
+around 100 ms. This is when time-stretching is used. If the rate
+transposing effect alone is used, the latency requirement is much
+shorter, see section 'About algorithms'. </li>
+  <li> Processing CD-quality sound (16bit stereo sound with 44100H
+sample rate) in real-time or faster is possible starting from
+processors equivalent to Intel Pentium 133Mh or better, if using the
+"quick" processing algorithm. If not using the "quick" mode or if
+floating point sample data are being used, several times more CPU power
+is typically required.</li>
+</ul>
+<h3>3.3. About algorithms</h3>
+<p>SoundTouch provides three seemingly independent effects: tempo,
+pitch and playback rate control. These three controls are implemented
+as combination of two primary effects, <em>sample rate transposing</em>
+and <em>time-stretching</em>.</p>
+<p><em>Sample rate transposing</em> affects both the audio stream
+duration and pitch. It's implemented simply by converting the original
+audio sample stream to the&nbsp; desired duration by interpolating from
+the original audio samples. In SoundTouch, linear interpolation with
+anti-alias filtering is used. Theoretically a higher-order
+interpolation provide better result than 1st order linear
+interpolation, but in audio application linear interpolation together
+with anti-alias filtering performs subjectively about as well as
+higher-order filtering would.</p>
+<p><em>Time-stretching </em>means changing the audio stream duration
+without affecting it's pitch. SoundTouch uses WSOLA-like
+time-stretching routines that operate in the time domain. Compared to
+sample rate transposing, time-stretching is a much heavier operation
+and also requires a longer processing "window" of sound samples used by
+the processing algorithm, thus increasing the algorithm input/output
+latency. Typical i/o latency for the SoundTouch time-stretch algorithm
+is around 100 ms.</p>
+<p>Sample rate transposing and time-stretching are then used together
+to produce the tempo, pitch and rate controls:</p>
+<ul>
+  <li> <strong>'Tempo'</strong> control is implemented purely by
+time-stretching. </li>
+  <li> <strong>'Rate</strong>' control is implemented purely by sample
+rate transposing. </li>
+  <li> <strong>'Pitch</strong>' control is implemented as a
+combination of time-stretching and sample rate transposing. For
+example, to increase pitch the audio stream is first time-stretched to
+longer duration (without affecting pitch) and then transposed back to
+original duration by sample rate transposing, which simultaneously
+reduces duration and increases pitch. The result is original duration
+but increased pitch.</li>
+</ul>
+<h3>3.4 Tuning the algorithm parameters</h3>
+<p>The time-stretch algorithm has few parameters that can be tuned to
+optimize sound quality for certain application. The current default
+parameters have been chosen by iterative if-then analysis (read: "trial
+and error") to obtain best subjective sound quality in pop/rock music
+processing, but in applications processing different kind of sound the
+default parameter set may result into a sub-optimal result.</p>
+<p>The time-stretch algorithm default parameter values are set by the
+following #defines in file "TDStretch.h":</p>
+<blockquote>
+  <pre>#define DEFAULT_SEQUENCE_MS     AUTOMATIC<br>#define DEFAULT_SEEKWINDOW_MS   AUTOMATIC<br>#define DEFAULT_OVERLAP_MS      8</pre>
+</blockquote>
+<p>These parameters affect to the time-stretch algorithm as follows:</p>
+<ul>
+  <li> <strong>DEFAULT_SEQUENCE_MS</strong>: This is the default
+length of a single processing sequence in milliseconds which determines
+the how the original sound is chopped in the time-stretch algorithm.
+Larger values mean fewer sequences are used in processing. In principle
+a larger value sounds better when slowing down the tempo, but worse
+when increasing the tempo and vice versa.&nbsp;<br>
+    <br>
+By default, this setting value is calculated automatically according to
+tempo value.<br>
+  </li>
+  <li> <strong>DEFAULT_SEEKWINDOW_MS</strong>: The seeking window
+default length in milliseconds is for the algorithm that seeks the best
+possible overlapping location. This determines from how wide a sample
+"window" the algorithm can use to find an optimal mixing location when
+the sound sequences are to be linked back together.&nbsp;<br>
+    <br>
+The bigger this window setting is, the higher the possibility to find a
+better mixing position becomes, but at the same time large values may
+cause a "drifting" sound artifact because neighboring sequences can be
+chosen at more uneven intervals. If there's a disturbing artifact that
+sounds as if a constant frequency was drifting around, try reducing
+this setting.<br>
+    <br>
+By default, this setting value is calculated automatically according to
+tempo value.<br>
+  </li>
+  <li> <strong>DEFAULT_OVERLAP_MS</strong>: Overlap length in
+milliseconds. When the sound sequences are mixed back together to form
+again a continuous sound stream, this parameter defines how much the
+ends of the consecutive sequences will overlap with each other.<br>
+    <br>
+This shouldn't be that critical parameter. If you reduce the
+DEFAULT_SEQUENCE_MS setting by a large amount, you might wish to try a
+smaller value on this.</li>
+</ul>
+<p>Notice that these parameters can also be set during execution time
+with functions "<strong>TDStretch::setParameters()</strong>" and "<strong>SoundTouch::setSetting()</strong>".</p>
+<p>The table below summaries how the parameters can be adjusted for
+different applications:</p>

+<h3>3.5 Performance Optimizations </h3>
+<p><strong>General optimizations:</strong></p>
+<p>The time-stretch routine has a 'quick' mode that substantially
+speeds up the algorithm but may degrade the sound quality by a small
+amount. This mode is activated by calling SoundTouch::setSetting()
+function with parameter&nbsp; id of SETTING_USE_QUICKSEEK and value
+"1", i.e. </p>
+<blockquote>
+  <p>setSetting(SETTING_USE_QUICKSEEK, 1);</p>
+</blockquote>
+<p><strong>CPU-specific optimizations:</strong></p>
+<ul>
+  <li> Intel MMX optimized routines are used with compatible CPUs when
+16bit integer sample type is used. MMX optimizations are available both
+in Win32 and Gnu/x86 platforms. Compatible processors are Intel
+PentiumMMX and later; AMD K6-2, Athlon and later. </li>
+  <li> Intel SSE optimized routines are used with compatible CPUs when
+floating point sample type is used. SSE optimizations are currently
+implemented for Win32 platform only. Processors compatible with SSE
+extension are Intel processors starting from Pentium-III, and AMD
+processors starting from Athlon XP. </li>
+  <li> AMD 3DNow! optimized routines are used with compatible CPUs when
+floating point sample type is used, but SSE extension isn't supported .
+3DNow! optimizations are currently implemented for Win32 platform only.
+These optimizations are used in AMD K6-2 and Athlon (classic) CPU's;
+better performing SSE routines are used with AMD processor starting
+from Athlon XP. </li>

+<ul>
+  <li> To use standard input/output pipes for processing, give "stdin"
+and "stdout" as input/output filenames correspondingly. The standard
+input/output pipes will still carry the audio data in .wav audio file
+format. </li>

+/// 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 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>
+
+Please read the WARNING, DISCLAIMER and PATENTS sections in this file.

+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 ?
+
+   See the CHANGES file.
+
+WHAT'S NEW IN 1.0.2 ?
+
+   See the CHANGES file.
+
+WHAT'S NEW IN 1.0.3 ?

-Introduction
-============
-
-  The FreeType  Project is distributed in  several archive packages;
-  some of them may contain, in addition to the FreeType font engine,
-  various tools and  contributions which rely on, or  relate to, the
-  FreeType Project.
-
-  This  license applies  to all  files found  in such  packages, and
-  which do not  fall under their own explicit  license.  The license
-  affects  thus  the  FreeType   font  engine,  the  test  programs,
-  documentation and makefiles, at the very least.
-
-  This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
-  (Independent JPEG  Group) licenses, which  all encourage inclusion
-  and  use of  free  software in  commercial  and freeware  products
-  alike.  As a consequence, its main points are that:
-
-    o We don't promise that this software works. However, we will be
-      interested in any kind of bug reports. (`as is' distribution)
-
-    o You can  use this software for whatever you  want, in parts or
-      full form, without having to pay us. (`royalty-free' usage)
-
-    o You may not pretend that  you wrote this software.  If you use
-      it, or  only parts of it,  in a program,  you must acknowledge
-      somewhere  in  your  documentation  that  you  have  used  the
-      FreeType code. (`credits')
-
-  We  specifically  permit  and  encourage  the  inclusion  of  this
-  software, with  or without modifications,  in commercial products.
-  We  disclaim  all warranties  covering  The  FreeType Project  and
-  assume no liability related to The FreeType Project.
-
-
-  Finally,  many  people  asked  us  for  a  preferred  form  for  a
-  credit/disclaimer to use in compliance with this license.  We thus
-  encourage you to use the following text:
-
-   """
-    Portions of this software are copyright © <year> The FreeType
-    Project (www.freetype.org).  All rights reserved.
-   """
-
-  Please replace <year> with the value from the FreeType version you
-  actually use.

-Legal Terms
-===========
-
-0. Definitions
---------------
-
-  Throughout this license,  the terms `package', `FreeType Project',
-  and  `FreeType  archive' refer  to  the  set  of files  originally
-  distributed  by the  authors  (David Turner,  Robert Wilhelm,  and
-  Werner Lemberg) as the `FreeType Project', be they named as alpha,
-  beta or final release.
-
-  `You' refers to  the licensee, or person using  the project, where
-  `using' is a generic term including compiling the project's source
-  code as  well as linking it  to form a  `program' or `executable'.
-  This  program is  referred to  as  `a program  using the  FreeType
-  engine'.
-
-  This  license applies  to all  files distributed  in  the original
-  FreeType  Project,   including  all  source   code,  binaries  and
-  documentation,  unless  otherwise  stated   in  the  file  in  its
-  original, unmodified form as  distributed in the original archive.
-  If you are  unsure whether or not a particular  file is covered by
-  this license, you must contact us to verify this.
-
-  The FreeType  Project is copyright (C) 1996-2000  by David Turner,
-  Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
-  specified below.
-
-1. No Warranty

-  BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE INABILITY TO
-  USE, OF THE FREETYPE PROJECT.
-
-2. Redistribution
------------------
-
-  This  license  grants  a  worldwide, royalty-free,  perpetual  and
-  irrevocable right  and license to use,  execute, perform, compile,
-  display,  copy,   create  derivative  works   of,  distribute  and
-  sublicense the  FreeType Project (in  both source and  object code
-  forms)  and  derivative works  thereof  for  any  purpose; and  to
-  authorize others  to exercise  some or all  of the  rights granted
-  herein, subject to the following conditions:
-
-    o Redistribution of  source code  must retain this  license file
-      (`FTL.TXT') unaltered; any  additions, deletions or changes to
-      the original  files must be clearly  indicated in accompanying
-      documentation.   The  copyright   notices  of  the  unaltered,
-      original  files must  be  preserved in  all  copies of  source
-      files.
-
-    o Redistribution in binary form must provide a  disclaimer  that
-      states  that  the software is based in part of the work of the
-      FreeType Team,  in  the  distribution  documentation.  We also
-      encourage you to put an URL to the FreeType web page  in  your
-      documentation, though this isn't mandatory.
-
-  These conditions  apply to any  software derived from or  based on
-  the FreeType Project,  not just the unmodified files.   If you use
-  our work, you  must acknowledge us.  However, no  fee need be paid
-  to us.
-
-3. Advertising
---------------
-
-  Neither the  FreeType authors and  contributors nor you  shall use
-  the name of the  other for commercial, advertising, or promotional
-  purposes without specific prior written permission.
-
-  We suggest,  but do not require, that  you use one or  more of the
-  following phrases to refer  to this software in your documentation
-  or advertising  materials: `FreeType Project',  `FreeType Engine',
-  `FreeType library', or `FreeType Distribution'.
-
-  As  you have  not signed  this license,  you are  not  required to
-  accept  it.   However,  as  the FreeType  Project  is  copyrighted
-  material, only  this license, or  another one contracted  with the
-  authors, grants you  the right to use, distribute,  and modify it.
-  Therefore,  by  using,  distributing,  or modifying  the  FreeType
-  Project, you indicate that you understand and accept all the terms
-  of this license.
-
-4. Contacts
