[LAD] Hello World in LV2

Hi, Looking around the LV2 Trac at http://lv2plug.in/trac/, I don't see any simple introduction on how to create a minimal plugin. Is there any plan for this? I think that a gain plugin tutorial could be a way to show how to say Hello World in LV2. Something very short, which include proper links to reference documentation. Not a long story as "LV2 programming for the complete idiot" which IIUC also happens to be obsolete. In addition to helping the newbie find his way, one advantage of a short and simple tutorial is that it should be easy to maintain when LV2 evolves. And as an alternative or companion to the tutorial, the source code for a minimal (official) example would be great. I mean, the kind of example that you find in JACK source code. Does a such thing already exist? -- Olivier
