+# Set the proper macros based on whether we are making the debugging version
+# or not.  The valid parameters to this file are:
+#
+#	DEBUG=1		==> enable the making of the DBUG version
+#	DBMALLOC=1	==> enable DBUG version with extensive MALLOC checking
+#
+#	DB_CFLAGS	==> CFLAGS is set to this value at the end if DEBUG=1
+#	DB_LDFLAGS	==> LDFLAGS is set to this at the end if DEBUG=1
+#	DB_LDLIBS       ==> LDLIBS is set to this at end if DEBUG=1
+#
+# The non debug versions of the above three macros are:
+#
+#	NDB_CFLAGS
+#	NDB_LDFLAGS
+#	NDB_LDLIBS
+#
+# One of the set of three should have values set appropriately prior to
+# sourcing this file.
