For record, the generations of NTP programs should be credited not just 
to me. Mike Petry and Louis Mamakos at U Maryland built the first 
version circa 1988. Dennis Ferguson at U Toronto largely rebuilt what 
became Version 2 as documented in rfc1118. Lars Mathiesen rebuilt once 
again Version 3 slavishly obedient to rfc1305. Almost 50 people have 
contributed one time or another as documented on the copyright page. 
That page does not adequately credit the current maintainers who troll 
for bugs, secure the code and in general watch over the beast.
