Newbie question. When I am looking at a addon/plugin and I see the "require" this or "require" that for the plugin, is there a simple way I am missing of finding out if I already have what is required? For example, I searched on one of the requires and after reading 10 different google references I found out the require was already part of the ruby libraries.(so I assume I don't have to download it). In any case, it took me a long time to find that out. Is there a shorter way?
