#
# FUZZ testing uses a probabalistic grammar to generate
# pseudo-random requests which will be sent to a server
# over long periods of time, with the goal of turning up 
# garbage-input and buffer-overflow sensitivities.
#
# Each state ...
#       generates/chooses contents for variables
#       chooses a next state (from a weighted set of options)
#
# A terminal state is one from which there are no successors,
# at which point a message is generated (from the variables)
# and sent to the server.  
#
# The test program doesn't actually know (or care) what 
# response should be returned ... since the goal is to
# crash the server.
