-/**
- * This sample program should demonstrate certain aspects of debugging
- * standalone V8-based application.
- *
- * The program reads input stream, processes it line by line and print
- * the result to output. The actual processing is done by custom JavaScript
- * script. The script is specified with command line parameters.
- *
- * The main cycle of the program will sequentially read lines from standard
- * input, process them and print to standard output until input closes.
- * There are 2 possible configuration in regard to main cycle.
- *
- * 1. The main cycle is on C++ side. Program should be run with
- * --main-cycle-in-cpp option. Script must declare a function named
- * "ProcessLine". The main cycle in C++ reads lines and calls this function
- * for processing every time. This is a sample script:
-
-function ProcessLine(input_line) {
-  return ">>>" + input_line + "<<<";
-}
-
- *
- * 2. The main cycle is in JavaScript. Program should be run with
- * --main-cycle-in-js option. Script gets run one time at all and gets
- * API of 2 global functions: "read_line" and "print". It should read input
- * and print converted lines to output itself. This a sample script:
-
-while (true) {
-  var line = read_line();
-  if (!line) {
-    break;
-  }
-  var res = line + " | " + line;
-  print(res);
-}
-
- *
- * When run with "-p" argument, the program starts V8 Debugger Agent and
- * allows remote debugger to attach and debug JavaScript code.
- *
- * Interesting aspects:
- * 1. Wait for remote debugger to attach
- * Normally the program compiles custom script and immediately runs it.
- * If programmer needs to debug script from the very beginning, he should
- * run this sample program with "--wait-for-connection" command line parameter.
- * This way V8 will suspend on the first statement and wait for
- * debugger to attach.
- *
- * 2. Unresponsive V8
- * V8 Debugger Agent holds a connection with remote debugger, but it does
- * respond only when V8 is running some script. In particular, when this program
- * is waiting for input, all requests from debugger get deferred until V8
- * is called again. See how "--callback" command-line parameter in this sample
- * fixes this issue.
