Examples

Compress

Will compress all the files and directory present in /path/to/input to /path/to/output and will generate some files like archive.part.0, archive.part.1 ... archive.part.n where which chunk will have a size of 2MB

> scala scalarchiver.jar compress -i /path/to/input -o /path/to/output -s 2

Extract

Will take the chunk files from /path/to/input an extract their content to /path/to/output

> scala scalarchiver.jar extract -i /path/to/input -o /path/to/output

TODO

Improve exception management
Add some unit tests
Make the compression process run in parallel
