+ and first released with the early BSD UNIX versions. All of this work
+ was done by students at the University of California.
+
+ After graduation, one of those students went to work at AT&T Bell
+ Labs, and made an improved termcap library called terminfo (i.e.,
+ "libterm"). That was subsequently released in System V Release 2.
+ Thereafter, other developers added to the terminfo library. For
+ instance, a student at Cornell University wrote an improved terminfo
+ library as well as a tool (tic) to compile the terminal descriptions.
+ As a general rule, AT&T did not identify the developers in the
+ source-code or documentation; the tic and infocmp programs are the
+ exceptions.
+
+ System V Release 3 (System III UNIX) from Bell Labs featured a
+ rewritten and much-improved curses library,l along with the tic
+ program.
