Detailed Description

handles virtual packages

When a Provides: line is encountered a new provides record is added associating the package with a virtual package name. The provides structures are linked off the package structures. This simplifies the analysis of dependencies and other aspects A provides refers to a specific version of a specific package, not all versions need to provide that provides.
