debget | download/compile source and binary Debian packages | Mehr ...
debget downloads source and binary Debian packages by name. It doesn't require a local copy of the Packages files, instead it queries packages.debian.org to find out what versions are available. . debget can also optionally unpack and compile source packages, and even install the generated binary packages. If you intend to use these features you should install the devscripts package for the dscverify script it contains.
