    (description
     "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.")
