Description
This library provides the common functionality for searching and managing packages as well as information about packages. Higher-level package managers can depend upon this library.
This includes: * retrieval of information about packages from multiple sources * retrieval of packages and all dependent packages needed to satisfy a request either through an internal solver or by interfacing with an external one * authenticating the sources and validating the retrieved data * installation and removal of packages in the system * providing different transports to retrieve data over cdrom and http(s) as well as an interface to add more transports like tor+http(s) (apt-transport-tor).
