SentoWeb\Fabric is our compact PHP framework based on Illuminate (Laravel) and Symfony components.
The framework resides in the fabric.phar file located in the root directory of the application.
Should you want to inspect the source code of the framework, you can extract the PHAR file using a tool like UnPhar or an IDE which supports phar files (PhpStorm). You can also download the files in zip format by following the links in the version history.
The framework uses a modified composer autoloader to load the framework's dependencies from the fabric.phar/vendor/ directory and the parent application's dependencies from the vendor/ directory.
