+Typenum is a Rust library for type-level numbers evaluated at compile time. It
+currently supports bits, unsigned integers, and signed integers. It also
+provides a type-level array of type-level numbers, but its implementation is
+incomplete.
+
+This package contains library source intended for building other packages
+which use %{crate} from crates.io.
