-   * This module emits various events when state changes occur.  The basic event
-   * naming scheme is that event "X" means "X has changed" or "X is available".
-   * Some names are more detailed to clarify their precise meaning.
-   *
-   * The events this module may emit include:
-   *   before-project:
-   *     The selected project is about to change.  The event includes a special
-   *     |cancel| callback that will abort the project change if desired.
-   *   connection:
-   *     The connection status has changed (connected, disconnected, etc.)
-   *   install-progress:
-   *     A project being installed to a runtime has made further progress.  This
-   *     event contains additional details about exactly how far the process is
-   *     when such information is available.
-   *   project:
-   *     The selected project has changed.
-   *   project-started:
-   *     The selected project started running on the connected runtime.
-   *   project-stopped:
-   *     The selected project stopped running on the connected runtime.
-   *   project-removed:
-   *     The selected project was removed from the project list.
-   *   project-validated:
-   *     The selected project just completed validation.  As part of validation,
-   *     many pieces of metadata about the project are refreshed, including its
-   *     name, manifest details, etc.
-   *   runtime:
-   *     The selected runtime has changed.
-   *   runtime-apps-icons:
-   *     The list of URLs for the runtime app icons are available.
-   *   runtime-global-actors:
-   *     The list of global actors for the entire runtime (but not actors for a
-   *     specific tab or app) are now available, so we can test for features
-   *     like preferences and settings.
-   *   runtime-details:
-   *     The selected runtime's details have changed, such as its user-visible
-   *     name.
-   *   runtime-list:
-   *     The list of available runtimes has changed, or any of the user-visible
-   *     details (like names) for the non-selected runtimes has changed.
-   *   runtime-telemetry:
-   *     Detailed runtime telemetry has been recorded.  Used by tests.
-   *   runtime-targets:
-   *     The list of remote runtime targets available from the currently
-   *     connected runtime (such as tabs or apps) has changed, or any of the
-   *     user-visible details (like names) for the non-selected runtime targets
-   *     has changed.  This event includes |type| in the details, to distinguish
-   *     "apps" and "tabs".

-/**
- * Runtime and Scanner API
- *
- * |RuntimeScanners| maintains a set of |Scanner| objects that produce one or
- * more |Runtime|s to connect to.  Add-ons can extend the set of known runtimes
- * by registering additional |Scanner|s that emit them.
- *
- * Each |Scanner| must support the following API:
- *
- * enable()
- *   Bind any event handlers and start any background work the scanner needs to
- *   maintain an updated set of |Runtime|s.
- *   Called when the first consumer (such as WebIDE) actively interested in
- *   maintaining the |Runtime| list enables the registry.
- * disable()
- *   Unbind any event handlers and stop any background work the scanner needs to
- *   maintain an updated set of |Runtime|s.
- *   Called when the last consumer (such as WebIDE) actively interested in
- *   maintaining the |Runtime| list disables the registry.
- * emits "runtime-list-updated"
- *   If the set of runtimes a |Scanner| manages has changed, it must emit this
- *   event to notify consumers of changes.
- * scan()
- *   Actively refreshes the list of runtimes the scanner knows about.  If your
- *   scanner uses an active scanning approach (as opposed to listening for
- *   events when changes occur), the bulk of the work would be done here.
- *   @return Promise
- *           Should be resolved when scanning is complete.  If scanning has no
- *           well-defined end point, you can resolve immediately, as long as
- *           update event is emitted later when changes are noticed.
- * listRuntimes()
- *   Return the current list of runtimes known to the |Scanner| instance.
- *   @return Iterable
- *
- * Each |Runtime| must support the following API:
- *
- * |type| field
- *   The |type| must be one of the values from the |RuntimeTypes| object.  This
- *   is used for Telemetry and to support displaying sets of |Runtime|s
- *   categorized by type.
- * |id| field
- *   An identifier that is unique in the set of all runtimes with the same
- *   |type|.  WebIDE tries to save the last used runtime via type + id, and
- *   tries to locate it again in the next session, so this value should attempt
- *   to be stable across Firefox sessions.
- * |name| field
- *   A user-visible label to identify the runtime that will be displayed in a
- *   runtime list.
- * |prolongedConnection| field
- *   A boolean value which should be |true| if the connection process is
- *   expected to take a unknown or large amount of time.  A UI may use this as a
- *   hint to skip timeouts or other time-based code paths.
- * connect()
- *   Configure the passed |connection| object with any settings need to
- *   successfully connect to the runtime, and call the |connection|'s connect()
- *   method.
- *   @param  Connection connection
- *           A |Connection| object from the DevTools |ConnectionManager|.
- *   @return Promise
- *           Resolved once you've called the |connection|'s connect() method.
- * configure() OPTIONAL
- *   Show a configuration screen if the runtime is configurable.
