.dsc, a .orig.tar.gz, and a .debian.tar.xz (or .diff.gz). They allow creation of binary packages (.deb files described above) from the source code files of the program, which are written in a programming language.
.dsc (Debian Source Control) 文件是包括 RFC 2822 标头 (如同 control 文件于 第 5.2.1 节 “描述：control 文件”) 的简短文本档，描述原始软件包及包括的其他文件。由维护者签署，保证其真实性。详情见 第 6.5 节 “检查软件包真伪”。

编译-依赖），和那些二进制包依赖完全不同，因为它们需要设置编译软件所需工具的选项后，再来构建二进制包。
.orig.tar.gz 文件包括原开发者提供的源代码。要求 Debian 的软件包维护者不要修改它，以便检查原来的文件与集成后的文件 (比较校验码就知道) 并且尊重其他著者的意愿。
.debian.tar.xz contains all of the modifications made by the Debian maintainer, especially the addition of a debian directory containing the instructions to execute to construct a Debian package.
