<p>This manual documents the API used by C and C++ programmers who want to write
extension modules or embed Python. It is a companion to <a class="reference external" href="../extending/index.html#extending-index"><em>Extending and Embedding the Python Interpreter</em></a>,
which describes the general principles of extension writing but does not
document the API functions in detail.</p>
