+Here is a list of compile switches, used to customize Radiance code
+for specific machines and users:
-–
+-DMC            If set, switches from default low-discrepency sequence
-–
+                sampling to true (pseudorandom) Monte Carlo.  Use if
-–
+                the "brushed" appearance of specular highlights and
-–
+                penumbras bothers you.
-–
+-DALIGN=(type)  Alignment type, machine-dependent.  Most RISC
+                architectures align on 8-word boundaries (double).
+                The default alignment type is int.
+                Values greater than 20 use over 4 Kbytes per
+                light source, which can add up to a lot of
+                memory in scenes with many sources.
-+
-+
+-DAVGREFL=R     Set the average surface reflectance for the purpose
-+
+                of indirect irradiance calculations to R, where
-+
+                R is a real number in the range (0,1.0).  The
-+
+                default value is 0.50 (50%).  This value indirectly
-+
+                controls the maximum number of ambient bounces,
-+
+                which can never be more than the log of the -ad
-+
+                setting times the log of AVGREFL.
