-/* ######################################################################
-
- Bzip2 method - Take a file URI in and decompress it into the target
- file.
-
- While the method is named "bzip2" it handles also other compression
- types as it calls binaries based on the name of the method,
- so it can also be used to handle gzip, lzma and others if named
- correctly.
