How can I send "user defined" emails with the "new" trac.notification

I'm trying to migrate some plugins to Trac 1.3.2 (trunk) and stumble
upon the removed trac.notification NotfyEmail implementation that is
deprecated for a while now.
I have searched the trac api web pages and the trac development pages
where the new api is basically described. But for now I have still no
idea of how I could implement a substitution for the
NotifyEmail.notify() or NotifyEmail.send() functions to just send email
notifications. This feature is uses in many plugins and support for
those plugins will break with Trac 1.3.x (as an important example: the
AccountManager
<https://trac-hacks.org/wiki/AccountManagerPlugin?redirectedfrom=AccountManager>
plugin).
I would like to upgrade at least our own installations of those plugins
if some of you might be able to lead me in the right direction.
Cheers,

Depending on the plugin you might need the following:
1. Create a new subclass of NotificationEvent, or find an existing
subclass like TicketChangeEvent that contains the information you need.
Example:
https://trac.edgewall.org/browser/trunk/trac/ticket/notification.py?rev=15805&marks=63-74#L62
2. Create a new object instance of that NotificationEvent class, and
call NotificationSystem.notify().
Examples:
https://trac.edgewall.org/browser/trunk/trac/ticket/web_ui.py?rev=15943&marks=1356,1397#L1351
(Or call NotificationSystem.distribute_event() to circumvent
subscribers, but this is not the preferred way. If possible just add
more subscribers as needed.
Examples:
https://trac.edgewall.org/wiki/CookBook/Notification/Subscriptions
)
3. If you created a new NotificationEvent class, you also need to create
a new INotificationFormatter component implementation that formats such
events to emails.
Docs:
https://trac.edgewall.org/wiki/TracDev/PluginDevelopment/ExtensionPoints/trac.notification.api.INotificationFormatter
Example:
https://trac.edgewall.org/browser/trunk/trac/ticket/notification.py?rev=15805&marks=63-74#L94
The changes required for AccountManager should be discussed here:
https://trac-hacks.org/ticket/13124
