Supplemental:
undel does an in-place undelete of files and will recover entire
directory trees. undel will only recover files that are 'clean',
i.e. all blocks that the file had originally allocated must currently
be unused in the bitmap and all inode, extent, and directory blocks
are intact and consistent.  This ensures that the file system will not
be corrupted after files are recovered (chkfsys will not
complain). This does NOT mean that the contents of the undeleted file
will be the same as the original though -- this can occur if blocks
had been used for other purposes and subsequently released. As such,
undel is most useful for recovering files that have been recently
deleted.

See useage message for complete details.

Installation:

# gunzip undel.gz
# cksum undel

1. The undel executable must be located in the search PATH for recursive
   deletes to work.

2. In order to undelete, undel must have write access to the disk mount
   raw device (e.g. /dev/hd0t77).
