Where is documentation about the dpkg format? I'm looking for information about the data format of .deb files as well as the formats and usages of the various files in the architecture. I have tried parsing the sources of dpkg and lintian, but the former is rather confusing, since I didn't write it, and especially because I have a very unusual style of code-writing) and the latter is not in my language.
In particular, what references do the developers use? (Since Debian is GPL'ed, I assume it's not secret.) I hope they don't just keep it in their memory, because that can unfortunately lead to severe disorganization in certain circumstances.
