-/// A macro for defining `#[cfg]` match-like statements.

-/// The `cfg_select!` macro checks a series of `#[cfg]` conditions, and picks the branch that
-/// belongs to the first condition that evaluates to true.
+/// This macro evaluates, at compile-time, a series of `cfg` predicates, selects
+/// the first that is true, and emits the code guarded by that predicate. The

-/// An optional trailing `_` wildcard match arm can be used to specify a fallback branch.
-/// If none of the conditions evaluate to `true`, a compile error is emitted.
