+%description    devel
+The enum `Either` with variants `Left` and `Right` is a general purpose
+sum type with two cases.
+
+Either has methods that are similar to Option and Result, and it also implements
+traits like `Iterator`.
+
+Includes macros `try_left!()` and `try_right!()` to use for
+short-circuiting logic, similar to how the `?` operator is used with `Result`.
+Note that `Either` is general purpose. For describing success or error, use the
+regular `Result`.
+
+This package contains library source intended for building other packages
+which use %{crate} from crates.io.
