"learn" program

[Larry Broda]

Can anybody tell me where the "learn" program available on many BSD
systems comes from?  i.e., is it a Public Domain program and if so,
where I can get it , or is it a licensed product, etc?  I am running a
SUN 4/470 system and have gotten a request from my boss to find 
and install this utility, as we have many novice users here.
