Welcome to Excalibur Bzip2!
As always, the if you have any questions :
1) Make sure you followed any directions
2) Review documentation included in this package, or online at
http://jakarta.apache.org/avalon/excalibur
3) Ask on the avalon-dev list. This is a great source of support
information. To join, read http://jakarta.apache.org/site/mail.html
and then follow the link at the bottom to join the lists.

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