We use composer already to install SabreDAV. Include config composer.(json|lock) to install and manage more dependencies in future. Also provide PSR-4 autoloading for our namespaced classes, e.g. "Zotlabs\". To regenerate autoloader maps use: $ composer install --optimize-autoloader --no-dev We could also remove the whole vendor/ folder from our repository, but that would need changes in deployment and how to install hubs and needs more discussion first.
