+     "Cedille is an interactive theorem-prover and dependently typed
+programming language, based on extrinsic (aka Curry-style) type theory.  This
+makes it rather different from type theories like Coq and Agda, which are
+intrinsic (aka Church-style).  In Cedille, terms are nothing more than
+annotated versions of terms of pure untyped lambda calculus.  In contrast, in
+Coq or Agda, the typing annotations are intrinsic parts of terms.  The typing
+annotations can only be erased as an optimization under certain conditions,
+not by virtue of the definition of the type theory.")
