-Source packages consist of either two or three files: a

-or both an <filename>.orig.tar.gz</filename> and a
-<filename>.diff.gz</filename> file.

-If a package is developed specially for Debian and is not distributed outside
-of Debian, there is just one <filename>.tar.gz</filename> file which contains
-the sources of the program. If a package is distributed elsewhere too, the
-<filename>.orig.tar.gz</filename> file stores the so-called <literal>upstream
-source code</literal>, that is the source code that's distributed by the
-<literal>upstream maintainer</literal> (often the author of the software).
-In this case, the <filename>.diff.gz</filename> contains the changes made by
-the Debian maintainer.
