Linux: RPM Package

Description

The Linux: RPM Package test is used to check the RPM header information for a given RPM package.

The rpminfo_object element is used by a rpminfo_test to define the object to be evaluated. An rpm info object consists of a single name entity that identifies the package being checked.

The rpminfo_state element defines the different information that can be used to evaluate the specified rpm. This includes the architecture, epoch number, and version numbers. Most of this information can be obtained through the rpm function.
