Symfony Cache 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.
