"""Plugin to store additional content from other plugins.
This plugin does not do much on its own, it lets other plugins register
additional content to compute on the fly when asked, e.g. the Wikipedia
plugin can store the Web page of the definition they just gave so users
wanting to know more about a definition can use the "plus" function to get
the URL to the Web page.
There can be only one handle registered at one time by target (so by
channel, user, etc). External plugins use the `add_handler` to set the
current handler for a target.
