+.)l
+.(q
+.pp
+This document describes a package of C library functions
+which allow the user to:
+.ie t .ip \ \ \ \(bu
+.el .ip 1)
+update a screen with reasonable optimization,
+.ie t .ip \ \ \ \(bu
+.el .ip 2)
+get input from the terminal
+in a screen-oriented fashion,
+and
+.ie t .ip \ \ \ \(bu
+.el .ip 3)
+independent from the above, move the cursor optimally
+from one point to another.
+.pp
+These routines all use the
+\*(tc \*(db to describe the capabilities of the terminal.
+.)q
+.b Acknowledgements
+.pp
+This package would not exist
+without the work of Bill Joy,
+who,
+in writing his editor,
+created the capability to generally describe terminals,
+wrote the routines which read this \*(db,
+and, most importantly,
+those which implement optimal cursor movement,
+which routines I have simply lifted nearly intact.
+Doug Merritt and Kurt Shoens also were extremely important,
+as were both willing to waste time listening to me rant and rave.
+The help and/or support of
+Ken Abrams,
+Alan Char,
+Mark Horton,
+and
+Joe Kalash,
+was, and is,
+also greatly appreciated.
