+SUMMARY="Optional static typing for Python"
+DESCRIPTION="
+Add type annotations to your Python programs, and use mypy to type
+check them.  Mypy is essentially a Python linter on steroids, and it
+can catch many programming errors by analyzing your program, without
+actually having to run it.  Mypy has a powerful type system with
+features such as type inference, gradual typing, generics and union
+types.
