    Description

      Features:
      1) HAR-like Tool
      2) RAID5/RAID6 & pluggable interface to implement additional coding
      3) Enable to group blocks across files
      4) Portable across cluster since all necessary metadata is embedded

      While it was developed separately from HAR or RAID due to time constraints, it would make sense to integrate with either of them.
