c3270 3.2 is a derivative of x3270 3.2, which comes from several sources:
3270tool | V x3270 1.2 | +-----------------------+------------------------+ | | | V V V x3270 1.2-cutpaste-iso8859-1 x3270 2.65 x3270 3.1 | V x3270 3.2 | V c3270 3.2 [you are here]The original work was 3270tool, a 3270 emulator for Suntools (Sun's original proprietary windowing environment). This was developed by Robert Viduya at Georgia Tech, and is why GTRC's copyright notice is first.
3270tool was then ported to X11R4 by Jeff Sparkes, and given the name "x3270." This is why his name is second.
x3270 3.1 started with Jeff's x3270 version 1.2, and was made very much bigger by Paul Mattes, with contributions and suggestions by a number of users from the net.
x3270 then evolved into version 3.2, which is built much more modularly; a derivative of that version is this code, c3270.
