-/** @file patest_suggested_vs_streaminfo_latency.c
-    @ingroup test_src
-    @brief Print suggested vs. PaStreamInfo reported actual latency
-    @author Ross Bencina <rossb@audiomulch.com>
-
-    Opens streams with a sequence of suggested latency values
-    from 0 to 2 seconds in .5ms intervals and gathers the resulting actual
-    latency values. Output a csv file and graph suggested vs. actual. Run
-    with framesPerBuffer unspecified, powers of 2 and multiples of 50 and
-    prime number buffer sizes.
