-## readline.createInterface(options)
-
-Creates a readline `Interface` instance. Accepts an "options" Object that takes
-the following values:
-
- - `input` - the readable stream to listen to (Required).
-
- - `output` - the writable stream to write readline data to (Optional).
-
- - `completer` - an optional function that is used for Tab autocompletion. See
-   below for an example of using this.
-
- - `terminal` - pass `true` if the `input` and `output` streams should be
-   treated like a TTY, and have ANSI/VT100 escape codes written to it.
-   Defaults to checking `isTTY` on the `output` stream upon instantiation.
-
- - `historySize` - maximum number of history lines retained. Defaults to `30`.
-
-The `completer` function is given the current line entered by the user, and
-is supposed to return an Array with 2 entries:
-
- 1. An Array with matching entries for the completion.
-
- 2. The substring that was used for the matching.
-
-Which ends up looking something like:
-`[[substr1, substr2, ...], originalsubstring]`.
-
-Example:
-
-    function completer(line) {
-      var completions = '.help .error .exit .quit .q'.split(' ')
-      var hits = completions.filter(function(c) { return c.indexOf(line) == 0 })
-      // show all completions if none found
-      return [hits.length ? hits : completions, line]
-    }
-
-Also `completer` can be run in async mode if it accepts two arguments:
-
-    function completer(linePartial, callback) {
-      callback(null, [['123'], linePartial]);
-    }
-
-`createInterface` is commonly used with `process.stdin` and
-`process.stdout` in order to accept user input:
-
-    var readline = require('readline');
-    var rl = readline.createInterface({
-      input: process.stdin,
-      output: process.stdout
-    });
-
-Once you have a readline instance, you most commonly listen for the
-`"line"` event.
-
-If `terminal` is `true` for this instance then the `output` stream will get
-the best compatibility if it defines an `output.columns` property, and fires
-a `"resize"` event on the `output` if/when the columns ever change
-(`process.stdout` does this automatically when it is a TTY).
