+# Note: We're sourcing the driver file "main.tcl" rather than exec-ing
+#       wish because we want to see stderr and stdout messages when they
+#       written, rather than when the program completes.  It also eliminates
+#       one process waiting for the other to complete. If "exec" is needed, 
+#       then the following could be replaced with blt::bgexec.  It doesn't
+#       try to redirect stderr into a file.
