@SuperDicq @newt @fial Plus there's a lot of things put in tarballs which do not pass as Source Code, either by the GPL definition (preferred form of the work for making modifications to it) or by the OSI definition:
> The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed.
Which quite means that horrors like the autogenerated ./configure scripts from autotools aren't Source Code.
