This is a utility library to allow us to extract jar files from .pack.xz format.

The program can take three commandline arguments:

• -packxz filepath1.pack.xz,filepath2.pack.xz,... - Decompress and unpack the file(s) specified.
• -xz filepath1.xz,filepath2.xz,... - Decompress the file(s) specified.
• -pack filepath1.pack,filepath2.pack,... - Unpack the file(s) specified.

You can specify multiple files by separating the paths with , commas.
