6. Example 1

See testsuite/tests/basic-io/wc.ml:

• Implements the ``wc'' command
• In the testsuite, is called on its own source code, wc.ml

The test description at the beginning of wc.ml looks like this:

(* TEST
  arguments = "wc.ml"
*)

The program is compiled and executed, then its output is compared to ``wc.reference''.
