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