Conky & Lua

Thanks to this article I became aware of how flexible conky's Lua configuration format is - it is effectively a Lua script. This opens almost endless new possibilities that go far beyond mere modularisation. For example, I could grab values from the system and design my conky accordingly, like I hav.....
