  //      note 1: In 1.3.2 and earlier, this function wrote to the body of the document when it
  //      note 1: was called in webbrowsers, in addition to supporting XUL.
  //      note 1: This involved >100 lines of boilerplate to do this in a safe way.
  //      note 1: Since I can't imageine a complelling use-case for this, and XUL is deprecated
  //      note 1: I have removed this behavior in favor of just calling `console.log`
  //      note 2: You'll see functions depends on `echo` instead of `console.log` as we'll want
  //      note 2: to have 1 contact point to interface with the outside world, so that it's easy
  //      note 2: to support other ways of printing output.
