Hi John,
Two things worth noting are:
1) I only discovered this when someone reported a bug and this is that
in the freevo web-server we already have a list of all the current
plug-ins and it is automatically generated, i.e.:
http://localhost/help/plugins.rpy
plus Don's configuration tool
http://localhost/pluginconfig.rpy?current_group=tv
2) Wiki pages are easy to generate, i.e:
freevo plugins -wiki -i tv.ivtv_xine_tv
There are more possibilities too:
freevo plugins -wiki <plug-in type>
plug-in type is on of:
MainMenuPlugin, Plugin, DaemonPlugin, IdleBarPlugin, ItemPlugin,
MimetypePlugin, ScreenSaverPlugin
