  This simple example shows how to use the Bzip2 classes to compress and uncompress
  a file.<br>
  If the file is a bzip2 archive it will uncompress else it will compress the
  file.  <br>
  Compile it by running  <br>
  &nbsp; &nbsp;javac -classpath ../../build/lib/@dist.name@.jar *.java (Unix) 
   <br>
  or  <br>
  &nbsp; &nbsp;javac -classpath ..\..\build\lib\@dist.name@.jar *.java (Windows)<br>
  <br>
  Run it using the following to compress:<br>
  &nbsp; &nbsp; java -classpath ../../build/lib/@dist.name@.jar:. Bzip2Compress
  README.txt README.txt.bz2 (Unix)  <br>
  or    <br>
  &nbsp; &nbsp; java -classpath ..\..\build\lib\@dist.name@.jar;. Bzip2Compress
  README.txt README.txt.bz2 (Windows)  <br>
  <br>
  And the following to uncompress:<br>
  &nbsp;&nbsp; java -classpath ../../build/lib/@dist.name@.jar:. Bzip2Uncompress
  README.txt.bz2 README.txt (Unix)  <br>
  or    <br>
  &nbsp; &nbsp;java -classpath ..\..\build\lib\@dist.name@.jar;. Bzip2Uncompress
  README.txt.bz2 README.txt (Windows) <br>
