#The general idea is that you can specify within a single makefile
#what to compile in debug mode, single processor, and multi processor 
#(if available).  By setting DEBUG to yes or SINGLE to yes, you describe
#how ALL object files will be created.  By specifying the names of
#certain object files in UCDEBUG and UCSINGLE you can have a greater
#degree of control.
