                     40: This document describes a package of C library functions
                     41: which allow the user to:
                     42: .ie t .ip \ \ \ \(bu
                     43: .el .ip 1)
                     44: update a screen with reasonable optimization,
                     45: .ie t .ip \ \ \ \(bu
                     46: .el .ip 2)
                     47: get input from the terminal
                     48: in a screen-oriented fashion,
                     49: and
                     50: .ie t .ip \ \ \ \(bu
                     51: .el .ip 3)
                     52: independent from the above, move the cursor optimally
                     53: from one point to another.
                     54: .pp
                     55: These routines all use the
                     56: \*(tc \*(db to describe the capabilities of the terminal.

                     59: .pp
                     60: This package would not exist
                     61: without the work of Bill Joy,
                     62: who,
                     63: in writing his editor,
                     64: created the capability to generally describe terminals,
                     65: wrote the routines which read this \*(db,
                     66: and, most importantly,
                     67: those which implement optimal cursor movement,
                     68: which routines I have simply lifted nearly intact.
                     69: Doug Merritt and Kurt Shoens also were extremely important,
                     70: as were both willing to waste time listening to me rant and rave.
                     71: The help and/or support of
                     72: Ken Abrams,
                     73: Alan Char,
                     74: Mark Horton,
                     75: and
                     76: Joe Kalash,
                     77: was, and is,
                     78: also greatly appreciated.
