This simple example shows how to use the Bzip2 classes to compress and uncompress
22+
a file.<br>
23+
If the file is a bzip2 archive it will uncompress else it will compress the
24+
file. <br>
25+
Compile it by running <br>
26+
&nbsp; &nbsp;javac -classpath ../../build/lib/@dist.name@.jar *.java (Unix)
27+
<br>
28+
or <br>
29+
&nbsp; &nbsp;javac -classpath ..\..\build\lib\@dist.name@.jar *.java (Windows)<br>
30+
<br>
31+
Run it using the following to compress:<br>
32+
&nbsp; &nbsp; java -classpath ../../build/lib/@dist.name@.jar:. Bzip2Compress
33+
README.txt README.txt.bz2 (Unix) <br>
34+
or <br>
35+
&nbsp; &nbsp; java -classpath ..\..\build\lib\@dist.name@.jar;. Bzip2Compress
36+
README.txt README.txt.bz2 (Windows) <br>
37+
<br>
38+
And the following to uncompress:<br>
39+
&nbsp;&nbsp; java -classpath ../../build/lib/@dist.name@.jar:. Bzip2Uncompress
40+
README.txt.bz2 README.txt (Unix) <br>
41+
or <br>
42+
&nbsp; &nbsp;java -classpath ..\..\build\lib\@dist.name@.jar;. Bzip2Uncompress
