nas-doc 1.9.3-4 (amd64 binary) in ubuntu precise

 The Network Audio System (NAS) was developed by NCD for playing,
 recording, and manipulating audio data over a network. Like the X
 Window System, it uses the client/server model to separate
 applications from the specific drivers that control audio input and
 output devices.

 This package contains the extra documentation provided with the NAS
 source, including PostScript copies of papers describing its design.
