# A tool to find superblocks in an EXT4 volume (probably easily adapted for EXT2,3)
# The usecase for this tool is likely pretty narrow...
# I have an LVM volume on a RAID array that was incorrectly reassembled (i.e. recreated)
# in the wrong order (I think), and I'm trying to recover from it, but it's unrecognizable
# as a filesystem since the primary superblock is missing. 
# This tool identifies all (seemingly) valid superblocks in a volume, though using them may
# introduce other errors if your filesystem is badly damaged. USE WITH CAUTION.
# The goal is to estimate how far offset the superblocks are and if disc order in the array
