In order for this to work, the plugin must use the maktaba flag API. Any plugin using the flag API can be configured by glaive.Maktaba is a vimscript library for plugin authors. It handles parsing the setting syntax, looking up the plugins, and applying the settings. Glaive itself is merely a thin wrapper around the hooks that maktaba provides: any plugin can sport a similar interface with minimal effort. Plugin manager plugins in particular are encouraged to do so.
