This is the Debian GNU/Linux package of Gene Kim's and Eugene
Spafford's Tripwire utility.

Tripwire is a tool that aids system administrators and users in
monitoring a designated set of files for any changes.  Used with
system files on a regular (e.g., daily) basis, Tripwire can notify
system administrators of corrupted or tampered files, so damage
control measures can be taken in a timely manner.

The upstream tripwire source can be found at:
