+.SH DESCRIPTION
+.I Ped
+is an interactive drawing program for
+5620 terminals.
+A
+.I file
+argument is equivalent to
+an 
+.L e
+command as described below.
+Most features of
+.I ped
+are menu-controlled and self-explanatory; further details
+are in the reference.
+.PP
+Button 1 selects actions
+from a permanent menu and to draw or pick up an object.
+Button 3 terminates drawing actions or changes
+the permanent menu.
+Button 2 causes the permanent menu to revert to
+.LR basic .
+.PP
+The operation of
+.I ped
+is split between host and terminal.
+When a file is first read, it is kept on
+the host;
+.L bring in
+gets it to the 5620.
+.PP
+Option
+.B -f
+causes
+.I ped
+to display all text in one size to save time and space.
+.PP
+Some of the actions on permanent menus (switched by button 3)
+are described below.
+The last action is usually remembered and may be
+executed repeatedly
+until another is selected.
+Thus, for example, one can fill many polygons with
+one button click per polygon.
+Actions marked
+.L (t)
+in the menu toggle on and off.
