Dumps all message state from the sup index to standard out. You can
later use sup-sync --restored --restore <filename> to recover the index.

This tool is primarily useful in the event that a Sup upgrade breaks index
format compatibility.

Usage:
  sup-dump > <filename>
  sup-dump | bzip2 > <filename> # even better
