+Marionette [ ˌmarɪəˈnɛt] is
+
+ * a puppet worked by strings: the bird bobs up and down like
+ a marionette;
+
+ * a person who is easily manipulated or controlled: many officers
+ dismissed him as the mayor’s marionette;
+
+ * the remote protocol that lets out-of-process programs communicate
+ with, instrument, and control Gecko-based browsers.
+
+Marionette provides interfaces for interacting with both the internal
+JavaScript runtime and UI elements of Gecko-based browsers, such
+as Firefox on desktop and mobile. It can control both the chrome- and content
+documents, giving a high level of control and ability to replicate,
+or emulate, user interaction.
+
+Head on to the Marionette documentation to find out more:

+ * This helper function (and its companion object) are used by bulk
+ * senders and receivers to read and write data in and out of other streams.
+ * Functions that make use of this tool are passed to callers when it is
+ * time to read or write bulk data. It is highly recommended to use these
+ * copier functions instead of the stream directly because the copier
+ * enforces the agreed upon length. Since bulk mode reuses an existing
+ * stream, the sender and receiver must write and read exactly the agreed
+ * upon amount of data, or else the entire transport will be left in a
+ * invalid state. Additionally, other methods of stream copying (such as
+ * NetUtil.asyncCopy) close the streams involved, which would terminate
+ * the debugging transport, and so it is avoided here.
+ *
+ * Overall, this *works*, but clearly the optimal solution would be
+ * able to just use the streams directly. If it were possible to fully
+ * implement nsIInputStream/nsIOutputStream in JS, wrapper streams could
+ * be created to enforce the length and avoid closing, and consumers could
+ * use familiar stream utilities like NetUtil.asyncCopy.
+ *
+ * The function takes two async streams and copies a precise number
+ * of bytes from one to the other. Copying begins immediately, but may
+ * complete at some future time depending on data size. Use the returned

+To run the tests in this directory, from the top source directory,
+either invoke the test despatcher in mach:
+
+ % ./mach test remote/marionette/test/xpcshell
+
+Or call out the harness specifically:
+
+ % ./mach xpcshell-test remote/marionette/test/xpcshell
+
+The latter gives you the --sequential option which can be useful
+when debugging to prevent tests from running in parallel.
+
+When adding new tests you must make sure they are listed in
+xpcshell.ini, otherwise they will not run on try.
+
+See also ../../doc/Testing.md for more advice on our other types of tests.

+ * An adapter that handles data transfers between the debugger client
+ * and server. It can work with both nsIPipe and nsIServerSocket
+ * transports so long as the properly created input and output streams
+ * are specified. (However, for intra-process connections,
+ * LocalDebuggerTransport, below, is more efficient than using an nsIPipe
+ * pair with DebuggerTransport.)
+ *
+ * @param {nsIAsyncInputStream} input
+ * The input stream.
+ * @param {nsIAsyncOutputStream} output
+ * The output stream.
+ *
+ * Given a DebuggerTransport instance dt:
+ * 1) Set dt.hooks to a packet handler object (described below).
+ * 2) Call dt.ready() to begin watching for input packets.
+ * 3) Call dt.send() / dt.startBulkSend() to send packets.
+ * 4) Call dt.close() to close the connection, and disengage from
+ * the event loop.
+ *
+ * A packet handler is an object with the following methods:
+ *
+ * - onPacket(packet) - called when we have received a complete packet.
+ * |packet| is the parsed form of the packet --- a JavaScript value, not
+ * a JSON-syntax string.
+ *
+ * - onBulkPacket(packet) - called when we have switched to bulk packet
+ * receiving mode. |packet| is an object containing:
+ * actor: Name of actor that will receive the packet
+ * type: Name of actor's method that should be called on receipt
+ * length: Size of the data to be read
+ * stream: This input stream should only be used directly if you
+ * can ensure that you will read exactly |length| bytes and
+ * will not close the stream when reading is complete
+ * done: If you use the stream directly (instead of |copyTo|
+ * below), you must signal completion by resolving/rejecting
+ * this deferred. If it's rejected, the transport will
+ * be closed. If an Error is supplied as a rejection value,
+ * it will be logged via |dump|. If you do use |copyTo|,
+ * resolving is taken care of for you when copying completes.
+ * copyTo: A helper function for getting your data out of the
+ * stream that meets the stream handling requirements above,
+ * and has the following signature:
+ *
+ * - params
+ * {nsIAsyncOutputStream} output
+ * The stream to copy to.
+ * - returns {Promise}
+ * The promise is resolved when copying completes or
+ * rejected if any (unexpected) errors occur. This object
+ * also emits "progress" events for each chunk that is
+ * copied. See stream-utils.js.
+ *
+ * - onClosed(reason) - called when the connection is closed. |reason|
+ * is an optional nsresult or object, typically passed when the
+ * transport is closed due to some error in a underlying stream.
+ *
+ * See ./packets.js and the Remote Debugging Protocol specification for
+ * more details on the format of these packets.
