> Sometimes is useful to have a tool to migrate files from a new version to an
> old version (e.g. convert a new XYZ encoded/compressed file to an old
> "uncompressed" format)
> also it will be useful to been able to recover an hfile from a corrupted

> try to recover as much as possible from the file by reading data blocks.
