Timing compilation

Hello, I would like to collect information about the time it takes to compile an ASDF system (possibly also load it), dependencies excluded. I'm thinking there's probably a way to do this by :around'ing compile-op, or something like that, but if someone already has a clear view on how to make this happen, I'd be grateful for the time spared! Thanks. -- Resistance is futile. You will be jazzimilated. Lisp, Jazz, Aïkido: http://www.didierverna.info
