%global _description %{expand:
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.}
