  Test code (tests.html) requires JsUnit
  Benchmark code needs prototype.js
  If you want to test and benchmark msgpack.js,
    please deploy as follows:
        ./lib/msgpack.js
        ./test/test_unpack.html
        ./test/test_pack.html
        ./test/test_xhr.html
        # see jsunit < https://github.com/pivotal/jsunit >
        ./test/jsunit/testRunner.html 
        ./test/jsunit/app/jsUnitCore.js
        ./test/jsunit/testRunner.html
        ./test/jsunit/app/jsUnitCore.js
        ./benchmark/benchmark.html
        # see prototype.js < https://www.prototypejs.org/ >
        ./benchmark/prototype/prototype.js
  Before you test test_xhr.html, you must start server.rb.
