Smurfs are little blue creatures about the size of an apple in
height and live in a forest, safe from the evil plots of a nasty wizard
and his cat. They typically manifest on cartoon networks.
Bluntly, they have nothing to do with Software Reliability, or
the work of Dr. William Farr,
who wrote a package called
SMERFS (spelled with an E, not a U).
If you're looking for modeling tools for software, hardware, and
system reliability, then you're at the right place.
