%description
nanobind is a small binding library that exposes C++ types in Python
and vice versa.  It is reminiscent of Boost.Python and pybind11 and
uses near-identical syntax.  In contrast to these existing tools,
nanobind is more efficient: bindings compile in a shorter amount of
time, produce smaller binaries, and have better runtime performance.

This package contains the Python module.
