+\r
+In this case I am suggesting that to start with the default deduping is\r
+unconditionally done and that there is no command line argument. We can\r
+decide on other filter options, possibly including a completely\r
+unfiltered list (*), later.\r

+(*) Personally I don't really see a use case for the unfiltered list but\r
