README.md000064400000000532151520414030006016 0ustar00Symfony EventDispatcher Contracts
=================================

A set of abstractions extracted out of the Symfony components.

Can be used to build on semantics that the Symfony components proved useful and
that already have battle tested implementations.

See https://github.com/symfony/contracts/blob/main/README.md for more information.
