class PluginDownloader(callbacks.Plugin):
"""
This plugin allows you to install unofficial plugins from
multiple repositories easily. Use the "repolist" command to see list of
available repositories and "repolist <repository>" to list plugins,
which are available in that repository. When you want to install a plugin,
just run command "install <repository> <plugin>".
First start by using the `plugindownloader repolist` command to see the
available repositories.
To see the plugins inside repository, use command
`plugindownloader repolist <repository>`
When you see anything interesting, you can use
`plugindownloader info <repository> <plugin>` to see what the plugin is
for.
And finally to install the plugin,
`plugindownloader install <repository> <plugin>`.
