+  <longdescription>
+    llvmlite uses the LLVM library for JIT (just-in-time) compilation of
+    Python code into native machine instructions during runtime. Instead
+    of exposing large parts of the LLVM C++ API for direct calls into the
+    LLVM library, llvmlite follows a lightweight multi-layered approach.
