bootstrap.phpfile (just like all the other modules, actually) and it is defined in the
composer.jsonfile as an autoload target. Since every single other module also depends on the Bootstrapper module, Composer's autoloader will ensure this file is the first one to load across the entire framework.
bootstrap-functions.phpcontains the checker function. The main logic is handled by the very simple
DWS_WP_FRAMEWORK_BOOTSTRAPPER_INITis set to true, otherwise it is set to false in
bootstrap.php. It is best to not access the constant directly, but through use of the helper function
requirements-error.phptemplate as an admin notice. This notice will contain the name of the module that failed to initialize and provide some more information about what went wrong.
