Message understood :-)

Btw, I'm bringing this up because, currently, the only way to build the 
plugin is through the IDE itself, which, while not unreasonable (after 
all you have to have an IDE if you want to use the plugin :-)), it 
require some configuration and I've seen people getting stuck quite 
frequently - a build command would probably mitigate some of those concerns.
