The main package is "ded", short for "Directory Editor".
A better name would be "graphical shell".  It is
described in ded.nroff.

The undocumented routines are:
dump.c -- Same old routine, but reports the i-number of phase errors.
fsin.s -- Abstracted from the ARL 11/40 fortran, this
          is a C-callable 11/40 f.p. sine/cosine routine.
at.c, inf_at.c -- These are here as samples for those who
		want to try installing "ded".  The one
		graphical call made by ded (aside from "erase",
		which clears the screen, if called with
		no arguments, or erases "argument" character
		positions from the current position) is "at",
		which positions the cursor.  It is called
		with a single numerical argument.  The
		argument mod 100 is the number of character
		positions over, and int(arg/100) is the
		number of lines down.  Thus, 103 is
		first line, three over, and 2315 is twenty-
		third line, 15 positions over.
		"at.c" is for AG-60 plasma panel
		terminals, and "inf_at.c" is for Infoton
		Vistar II's.
