+# This module provides automagic dependency generation along the
+# lines suggested in the GNU make.info
+
+# set MKDEP_MK=auto.dep.mk and dep.mk will include us
+
+# This version differs from autodep.mk, in that 
+# we use ${.TARGET:T}.d rather than ${.TARGET:T:R}.d
+# this makes it simpler to get the args to -MF and -MT right
+# and ensure we can simply include all the .d files.
+# 
+# However suffix rules do not work with something like .o.d so we
+# don't even try to handle 'make depend' gracefully.
+# dep.mk will handle that itself.
