[LAD] minimal LV2

I've been reading the LV2 docs for the N-th time, as well as lots of examples, and it all remains complete completely incomprehensible to my problably too primitive mind. So I have a simple question: What is the absolute minimum required to define an LV2 plugin (in other words, which files, and what do they need to contain) assuming the following: - The plugin requires one 'extension'. - This extension defines everything except whatever is required to enable a host to discover the existence of the plugin on a system. - In other words the extension defines how the host is supposed to instantiate and call the plugin, the way ports and parameter are described, etc. etc. Ciao, -- FA O tu, che porte, correndo si ? E guerra e morte !
