%global _description %{expand:
LibCST parses Python source code as a CST tree that keeps all formatting
details (comments, whitespaces, parentheses, etc). It's useful for building
automated refactoring (codemod) applications and linters.

LibCST creates a compromise between an Abstract Syntax Tree (AST) and a
traditional Concrete Syntax Tree (CST). By carefully reorganizing and naming
node types and fields, it creates a lossless CST that looks and feels like an
AST.}
