+README for PABLIO
+Portable Audio Blocking I/O Library
+Author: Phil Burk
+
+PABLIO is a simplified interface to PortAudio that provides
+read/write style blocking I/O.
+
+PABLIO is DEPRECATED. We recommend that people use the blocking I/O calls
+that are now part of the PortAudio API. These are Pa_ReadStream() and
+Pa_WriteStream().
+
