CSound

This release adds an updated manual, a new plugin system, use of
external libraries where possible (libsndfile for audio file I/O, one
of ALSA, PortAudio, CoreAudio, MME, or ASIO for realtime audio), support
for PortMIDI, Open Sound Control facilities via liblo, and Python/Java
bindings for the API. A number of opcodes from csoundAV and csoundVST
are now part of the main system.

This version comes with extensive internal changes
which allows the use of 32-Bit variables (previously,
only 16-bit indexes were used). This allows for much
larger and more complex instruments to be written. It
also comes with many new and modified opcodes, as
well as lots of bugfixes. It is now built as a shared
library, and the Csound API has been extensively
revised with new functions and structures.

Many new features were added.
