/**
* This is a C-linkage interface to the Rubber Band time stretcher.
*
* This is a wrapper interface: the primary interface is in C++ and is
* defined and documented in RubberBandStretcher.h. The library
* itself is implemented in C++, and requires C++ standard library
* support even when using the C-linkage API.
*
* Please see RubberBandStretcher.h for documentation.
*
* If you are writing to the C++ API, do not include this header.
