// The two files accompanying this benchmark contain a modified version of the
// Typescript compiler. They can be generated using the following instructions
// with the code available at:
//    http://typescript.codeplex.com/SourceControl/changeset/view/258e00903a9e
//
// 1) Copy the compiler from $TYPESCRIPT/bin/tsc.js to typescript-compiler.js
// 2) Remove the call to the batch compiler from the last line of tsc.js
// 3) Add this code after line 7963 (fix for Mozilla Firefox):
//    if (this.currentToken === undefined)
//      this.currentToken = this.scanner.scan();
// 4) Add this code after line 9142 (fix for Mozilla Firefox):
//    if (this.currentToken === undefined) {
//      this.currentToken = this.scanner.scan();
//      continue;
//    }
// 5) Generate the Typescript compiler input using the following command:
//    $ cat $TYPESCRIPT/src/compiler/*.ts | iconv -c -f utf8 -t ascii \
//      | dos2unix > /tmp/compiler_input
// 6) Run the following Python script to generate the reformatted input:
//    $ python script.py > typescript-input.js
//
// #!/usr/bin/env python
// import re;
// def escape_and_format(data, varname):
//   data = data.replace("\\", "\\\\").replace("\"", "\\\"")
//          .replace("\n", "\\n");
//   data = "var " + varname + " = \"" + data + "\""
//   print data; 
// result = open("/tmp/compiler_input", 'r');
// escape_and_format(result.read(), "compiler_input")
//

// compiler source at the time this benchmark was generated:
