+Configuring ASCII Pipe Buffer Size
+==================================

+This example mirrors the one above but also sets a ```pipe_buffer_size``` of
+1024 * 1024 for the pipe. This can be set on a per-pipe basis but is not 
+available on FreeBSD dists of ATS. If this field is not set, the pipe buffer
+will default to the OS default size.
