+ 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.
