 Added cct_x(t) and cct_y(t) to src/cal/cal/blackbody.cal to interpolate
 CIE chromaticities for particular black-body temperatures.
+
+Increased maximum number of input pictures in pcomb and pcompos to 512.
+
+Created rtcontrib program for computing ray contribution coefficients.
+This tool may be used to do standard optical ray tracing or daylight
+coefficient calculations for annual simulations, among other uses.
+
+Added tilde ('~') output option as part of the -o* specification of
+rtrace.  This permits ray trees to be parsed more easily in binary
+output mode, as needed by rtcontrib.
+
+Implemented Russian roulette ray termination with -lr <= 0.
+Made -lr -10 the default in rtcontrib.
+
+Made rtcontrib -f option search RAYPATH directories.
+
+Made it so -o option of rtcontrib can pipe -o output to a command.
+
+Added -if and -of options to total for binary i/o (following rcalc mold).
+
+Switched default options in rtrace to use Russian roulette.  (Rpict and rvu
+still use biased ray termination.)
+
+Added rtcontrib -r option to recover partial output.
+
+Added -R rendering option for pure Monte Carlo sampling.
+(Got rid of -DMC compile option, whicht his makes superfluous.)
