Appendix B. Using Red Hat Enterprise Linux packages

This section describes how to use software delivered as RPM packages for Red Hat Enterprise Linux.

B.1. Overview

A component such as a library or server often has multiple packages associated with it. You do not have to install them all. You can install only the ones you need.

The primary package typically has the simplest name, without additional qualifiers. This package provides all the required interfaces for using the component at program run time.

Packages with names ending in -devel contain headers for C and C++ libraries. These are required at compile time to build programs that depend on this package.

Packages with names ending in -docs contain documentation and example programs for the component.
