//
// 1) Copy the compiler from $TYPESCRIPT/bin/tsc.js to typescript-compiler.js

// 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("\"", "\\\"")
