+%description
+``wavio`` is a Python module that defines two functions:
+* ``wavio.read`` reads a WAV file and returns an object that holds the
+  sampling rate, sample width (in bytes), and a numpy array containing the
+  data.
+* ``wavio.write`` writes a numpy array to a WAV file, optionally using a
+  specified sample width.
+The functions can read and write 8-, 16-, 24- and 32-bit integer WAV files.
+The module uses the ``wave`` module in Python's standard library, so it has
+the same limitations as that module.  In particular, the ``wave`` module
+does not support compressed WAV files, and it does not handle floating
+point WAV files.  When floating point data is passed to ``wavio.write`` it
+is converted to integers before being written to the WAV file.
+``wavio`` requires Python 3.7 or later.
+``wavio`` depends on numpy (http://www.numpy.org).  NumPy version 1.19.0 or
+later is required.    The unit tests in ``wavio`` require ``pytest``.
+The API of the functions in ``wavio`` should not be considered stable.  There
+may be backwards-incompatible API changes between releases.
+*Important notice*
+In version 0.0.5, the data handling in ``wavio.write`` has been changed in
+a backwards-incompatible way.  The API for scaling the input in 0.0.4 was
+a flexible interface that only its creator could love.  The new API is
+simpler, and it is hoped that it does the right thing by default in
+most cases.  In particular:
+* When the input data is an integer type, the values are not scaled or
+  shifted.  The only change that might happen is the data will be clipped
+  if the values do not fit in the output integer type.
+* If the input data is a floating point type, ``sampwidth`` must be given.
+  The default behavior is to scale input values in the range [-1.0, 1.0]
+  to the output range [min_int+1, max_int], where min_int and max_int are
+  the minimum and maximum values of the output data type determined by
+  ``sampwidth``.  See the description of ``scale`` in the docstring of
+  ``wavio.write`` for more options.  Regardless of the value of ``scale``,
+  the float input 0.0 is always mapped to the midpoint of the output type;
+  ``wavio.write`` will not translate the values up or down.
+* A warning is now generated if any data values are clipped.  A parameter
+  allows the generation of the warning to be disabled or converted to an
+  exception.
+Example
+~~~~~~~
+The following code (also found in the docstring of ``wavio.write``) writes
+a three second 440 Hz sine wave to a 24-bit WAV file::
+    import numpy as np
+    import wavio
+    rate = 22050           # samples per second
+    T = 3                  # sample duration (seconds)
+    n = int(rate*T)        # number of samples
+    t = np.arange(n)/rate  # grid of time values
+    f = 440.0              # sound frequency (Hz)
+    x = np.sin(2*np.pi * f * t)
