+               Langkit (nickname for language kit) is a tool whose purpose is to make
+               it easy to create syntactic and semantic analysis engines. Write a
+               language specification in our Python DSL and Langkit will generate for
+               you an Ada library with bindings for the C and Python programming
+               languages.
+               The generated library is meant to provide a basis to write tooling,
+               including tools working on potentially changing and incorrect code,
+               such as IDEs.
