+theory. The λΠ-calculus is an extension of the simply typed λ-calculus with
+dependent types. The λΠ-calculus modulo theory is itself an extension of the
+λΠ-calculus where the context contains variable declaration as well as rewrite
+rules. This system is not designed to develop proofs, but to check proofs
+developed in other systems. In particular, it enjoys a minimalistic syntax.")
