+		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.
