This rails app show-cases the Solidus event subscribers autoload feature.
It can be used to prove that the feature is properly working before merging the relevant PRs on Solidus core and Solidus Support projects.
A simple even subscriber is defined within the app, and another one is defined
into the vendored version of solidus_auth_devise in vendor/gems. These
subscribers will add content to the output coming from the website homepage.
Also, the output will confirm that Solidus core subscribers are correctly loaded.
A further step in verifying everything works fine is to edit those subscribers output text and verify that the updated content is shown on the homepage.
