# What is libzypp?

libzypp provides all the functionality for a package manager:

- An API for package repository management, supporting most common repository metadata formats and signed repositories.
- An API for solving packages, products, patterns and patches (installation, removal, update and distribution upgrade operations) dependencies, with additional features like locking.
- An API for commiting the transaction to the system over a rpm target. Supporting deltarpm calculation, media changing and installation order calculation.
- An API for browsing available and installed software, with some facilities for programs with an user interface.
- A suite of maintained solving testcases representing common and uncommon operations on Linux software management

# Implementation

libzypp is implemented as a C++ library.

# Other functionality offered by libzypp

Most of libzypp functionality is implemented over components provided also by libzypp:

- Media abstraction library offering a common interface over local files, http,ftp,iso,nfs and other protocols.

# 3rd party software libzypp is based on

Additionally, some functionality libzypp uses is based on 3rd party libraries:

- SAT solver library, for dependency solving and repository data storage and querying
- curl, that powers some protocols of the media abstraction component
- boost, for misc. utilities like shared pointers, functors and algorithms.
