dget

dget is a toold to download Debian packages.

It can download the whole of a SourcePackage for a URL of a .changes or .dsc file. This is very useful for ?Sposoring or ?PackageChecking. If you use the -x option the package is also unpacked using dpkg-source.

It can also download binary packages from the ?Mirror like apt would do, but is more convenient. Just pass it the name of the package rather than a URL. An exact version can be retrieved (if available) by suffixing the package name with =version where version is the full ?VersionNumber of the desired version.
