+xtensor is a C++ library meant for numerical analysis with multi-dimensional
+array expressions.
+
+xtensor provides:
+* an extensible expression system enabling lazy broadcasting
+* an API following the idioms of the C++ standard library
+* tools to manipulate array expressions and build upon xtensor
