Extensions
PHPCompatInfo can be extended by registering objects that implement one or more of the following interfaces:
BeforeAnalysisInterfaceAfterAnalysisInterfaceBeforeFileAnalysisInterfaceAfterFileAnalysisInterfaceBeforeTraverseAstInterfaceAfterTraverseAstInterfaceBeforeProcessNodeInterfaceAfterProcessNodeInterfaceBeforeSetupSniffInterfaceAfterTearDownSniffInterfaceBeforeProcessSniffInterfaceAfterProcessSniffInterface
Furthermore, extensions may implement the Symfony\Component\EventDispatcher\EventSubscriberInterface in order to have its event handlers automatically registered with the EventDispatcher when the extension is loaded.
Polyfills
They are identified by services that implements the Bartlett\CompatInfo\Application\Polyfills\PolyfillInterface.
