stamp is a simple software system that allows you to take an md5-based snapshot of what a system looks like at a given
point (not quite an instant) in time.
You can also compare two such snapshots, to see what's changed.
I've used stamp for years for primarily two purposes:
I set up our autoinstall procedure to automatically stamp all systems installed, shortly after installation.
This makes it pretty easy to see what files have changed on a system since it was first installed - which is
especially useful, say, just prior to an upgrade.
I've also used it successfully, when installing misbehaved applications that like to scribble all over the system
disk rather than going into a single directory hierarchy, to get a list of files that the installation process
changes. Specifically, one would:
generate a stamp
install your software
generate another stamp
(automatically) compare the two stamps to see what's different
