This module implements functionality surrounding the package repository. The repository is the index of all packages known to the package manager. It contains metadata about the packages, such as their names, versions dependencies and where they can be acquired. The repository does not contain the actual packages. For a list of packages that are currently installed locally, you can consult the database.
