[H-GEN] Lightweight alternative to Tripwire?

[James Mills]

Hi Ben,

After reading what Tripwire does at a basic level (
http://en.wikipedia.org/wiki/Open_Source_Tripwire)
it seems to me that implementing such a tool yourself
doesn't seem all that hard and it wouldn't surprise me if
someone has already written several or more aolternatives.

For instnace:
