+/// @title DelegationSurrogateVotes
+/// @author [ScopeLift](https://scopelift.co)
+/// @notice A dead-simple contract whose only purpose is to hold governance tokens on behalf of
+/// users while delegating voting power to one specific delegatee. This is needed because a single
+/// address can only delegate its (full) token weight to a single address at a time. Thus, when a
+/// contract holds governance tokens in a pool on behalf of disparate token holders, those holders
+/// are typically disenfranchised from their governance rights.
+///
+/// If a pool contract deploys a DelegationSurrogateVotes for each delegatee, and transfers each
+/// depositor's tokens to the appropriate surrogate—or deploys it on their behalf—users can retain
+/// their governance rights.
+///
+/// The pool contract deploying the surrogates must handle all accounting. The surrogate simply
+/// delegates its voting weight and max-approves its deployer to allow tokens to be reclaimed.
