+     "@code{xeus} is a library meant to facilitate the implementation of
+kernels for Jupyter.  It takes the burden of implementing the Jupyter Kernel
+protocol so developers can focus on implementing the interpreter part of the
+kernel.
+
+Several Jupyter kernels are built upon @code{xeus}, such as @code{xeus-cling},
+a kernel for the C++ programming language, and @code{xeus-python}, an
+alternative Python kernel for Jupyter.")
