I used svp64 as prefix just becase the lib is called libsvp64. :-) I wanted it
to be called libresoc, but libibresoc sounds disguisting (although I know one
similar naming case). I think that'd be great to enforse this naming due to
popularisation. Other naming options are welcome, as long as they're short.
