This directory should contain distribution-provided configuration files extending /etc/entropy/repositories.conf content (only for "repository =" statements). Files are processed in lexical order. Filenames: ".keep", "README" are skipped and never considered. Files starting with "_" are considered belonging to disabled repositories. Files ending with ".example" are never considered. Files created by Entropy Client are prefixed with "entropy_". So, for example, for "sabayon-limbo" you will get: "entropy_sabayon-limbo".
