Three item classes are provided to provide functionality for
downloading of Index, Translation and Packages files.
- A Archive class is provided for downloading .deb files. It does Md5
+ A Archive class is provided for downloading .deb files. It does Hash
checking and source location as well as a retry algorithm.
