+      Twelf is a language used to specify, implement, and prove properties of
+      deductive systems such as programming languages and logics. Large
+      research projects using Twelf include the TALT typed assembly language,
+      a foundational proof-carrying-code system, and a type safety proof for
+      Standard ML.
