DIFF License

GNU DIFF was written by Mike Haertel, David Hayes, Richard Stallman
and Len Tower.  The basic algorithm is described in: "An O(ND)
Difference Algorithm and its Variations", Eugene Myers, Algorithmica
Vol. 1 No. 2, 1986, p 251.

Many bugs were fixed by Paul Eggert.  The unified diff idea and format
are from Wayne Davison.
