Local development - php-tuf/composer-stager GitHub Wiki
Composer Stager runs automated tests and a basic set of static analysis tools on CI, but it provides a more robust set of tools for local development. These exist in the /tools directory. To set them up, cd into the /tools directory, and run composer install. Run composer run-script from there to see the available tools. See also Automated-testing-&-analysis.
TODO: Explain the approach of using two composer.json files--one for production and main dev dependencies and a second in /tools for extra dev dependencies.
