+  <longdescription>
+    Cadabra is a symbolic computer algebra system (CAS) designed specifically
+    for the solution of problems encountered in field theory. It has extensive
+    functionality for tensor computer algebra, tensor polynomial simplification
+    including multi-term symmetries, fermions and anti-commuting variables,
+    Clifford algebras and Fierz transformations, component computations,
+    implicit coordinate dependence, multiple index types and many more.
+    The input format is a subset of TeX.
+    Both a command-line and a graphical notebook interface are available, and
+    you can also use Cadabra from Jupyter by using the Cadabra Jupyter kernel.
