A Package Source is either a folder or an HTTP service which contains package files, and allows for searching, downloading or uploading of package files. Currently, only folder-based package sources are implemented.
Multiple package sources can be defined, and they will be searched in the order they are defined. So when installing a package, if I don’t specify a package version, each registered package source will be searched, and the highest version chosen.
