"""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.
