+/**
+ *
+ * Allow xterm.js to handle ZMODEM uploads and downloads.
+ *
+ * This addon is a wrapper around zmodem.js. It adds the following to the
+ *  Terminal class:
+ *
+ * - function `zmodemAttach(<WebSocket>, <Object>)` - creates a Zmodem.Sentry
+ *      on the passed WebSocket object. The Object passed is optional and
+ *      can contain:
+ *          - noTerminalWriteOutsideSession: Suppress writes from the Sentry
+ *            object to the Terminal while there is no active Session. This
+ *            is necessary for compatibility with, for example, the
+ *            `attach.js` addon.
+ *
+ * - event `zmodemDetect` - fired on Zmodem.Sentry’s `on_detect` callback.
+ *      Passes the zmodem.js Detection object.
+ *
+ * - event `zmodemRetract` - fired on Zmodem.Sentry’s `on_retract` callback.
+ *
+ * You’ll need to provide logic to handle uploads and downloads.
+ * See zmodem.js’s documentation for more details.
+ *
+ * **IMPORTANT:** After you confirm() a zmodem.js Detection, if you have
+ *  used the `attach` or `terminado` addons, you’ll need to suspend their
+ *  operation for the duration of the ZMODEM session. (The demo does this
+ *  via `detach()` and a re-`attach()`.)
