		TRAD for Radiance by Greg Ward
			10/27/94

This directory contains a new graphical user interface to the Radiance
rad(1) program, called trad.  Trad depends on the existence of the Tcl/Tk
"wish" interpreter.  The source code for Tcl7.3 and Tk3.6 can be obtained
from ftp.cs.berkeley.edu in the /ucb/tcl directory.

Once wish has been installed, take the following steps to install trad:

	1) Create a tcl directory in the Radiance system library location
		(as determined by the setting of the LIBDIR variable in
		the rmake script -- type "grep LIBDIR= `which rmake`").
	2) Copy the files *.tcl *.hlp tclIndex and trad.icon to this
		new directory.
	3) Edit the file "trad", changing the variable "radlib" near
		the top to this new system library location.
	4) Copy trad to the Radiance executable directory.  (Try typing
		"which rview" if you don't know where that is.)
Optional:
	5) Install the trad.1 manual page in the appropriate location.
	6) Print it out using troff or psroff (or whatever), or send the
		PostScript version, "trad.ps" to a PostScript printer.
	7) If have troff or psroff and you want a hardcopy of the trad
		help screens, type "help2roff trad.hlp | troff -ms" or
		something like that.

Rehash and run trad.

Let me know of any bugs or problems.
