7 * The @tt{Mptop} module defines a simplified OCaml top-loop
8 * that is used by the @MetaPRL editor to evaluate user input.
9 * The evaluator handle only a few basic types (for example, for
10 * strings, numbers, terms, and tactics), and it handle function
11 * application. It does not implement more sophisticated OCaml
12 * expressions such as function definition and pattern matching.
