aMember Pro v.4 is based on Zend Framework's Zend_Controller and follow its guidelines. There is a Bootstrap class that handles all the dependencies and configuration loading.
To get all aMember Pro functions available for your custom script, just include bootstrap.php withing amember/ folder. It does not output any page, just initialises the core.
aMember Pro uses .htaccess file in root folder to route requests to pages. It is done by using of Apache's mod_rewrite by redirecting all requests for not-image files to amember/index.php . index.php runs Zend_Controller_Front routing procedures to include necessary controller class and run it.
