long_description = """
`typed_ast` is a Python 3 package that provides a Python 2.7 and Python 3
parser similar to the standard `ast` library.  Unlike `ast` below Python 3.8,
the parsers in
`typed_ast` include PEP 484 type comments and are independent of the version of
Python under which they are run.  The `typed_ast` parsers produce the standard
Python AST (plus type comments), and are both fast and correct, as they are
based on the CPython 2.7 and 3.7 parsers.

**Note:** The `ast` module of Python 3.8+ supports all features of `typed_ast`.
`typed_ast` does not support parsing code that uses syntax introduced in
Python 3.8 onwards.
We recommend using `ast` on Python 3.8 or above.
