Learn was originally written by Mike Lesk with some contributions from Brian Kernighan. The paper in this directory dates from the second version of learn, around 1979. This version of learn has been resurrected from the original V7 source and edited enough that the source compiles and the lessons can be executed. We have made no attempt to update the lessons, nor to fix some of the glaring problems with the code. Think of it as a historical document, not a polished system. cd src make learn
