+This directory contains Samba's very simple COM implementation.
+It is by no means finished yet.
+
+The main aim of this implementation is for use by our DCOM implementation,
+which lives in the dcom subdirectory. The local version is used mostly for
+testing.
+
+More information on this effort can be found in the DCOM whitepaper in
+the lorikeet repository.
