+/*	Changed 27/1/98 by DHM:
+	-----------------------
+	
+	Made LogFile derived from R_DumpContext rather than being a base class.
+
+	This is in order to give a clean interface for debug dumps to e.g. the
+	screen, with the same interface as to a log file.  This base class will
+	perform an analagous role to the class CDumpContext in the Microsoft
+	Foundation Class library.
+
+	The virtual functions dputs(), dprintf() and vdprintf() will eventually replace
+	lputs(), lprintf() and vlprintf().
+
+	For the moment I've copied and pasted the implementations of both.  I would prefer
+	in the short term to make one call the other, but this isn't easy with variable
+	arguments.  In the long term I want to eliminate the l* functions (lputs() etc)
+	but can't because of heritage code (and heritage libraries).
