 define Package/csound/description
 Csound is a sound design, audio synthesis, and signal processing system, providing facilities for music composition and performance on all major operating systems and platforms. Its use is not restricted to any style of music, having been employed for many years in the creation of classical, pop, techno, ambient, experimental, and (of course) computer music, as well as music for film and television.
