-/* ######################################################################
-
-   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.
