public function ExtensionDiscovery::scan in Composer Manager 8

Overrides BaseExtensionDiscovery::scan().

Compared to the parent method:

• doesn't scan core/ because composer_manager doesn't need to care about core extensions (core already ships with their dependencies).
• scans all sites (to accommodate the poor souls still using multisite).
