debian/copyright and Files-Within-Files

[Jonathan Yu <jonathan.i.yu@gmail.com>]

Hi all:

I realize DEP5 and all of that stuff regarding a machine-readable
copyright isn't set yet.

However, I've come across a case where tarballs contain files that
have various copyrights, and I'm not sure how to represent them in
d/copyright.

For example, if an upstream module contains a Stuff.tar.gz, and that
file itself contains stuff that is all under the same license, but has
different copyright information.

Assume Stuff.tar.gz contains files:
 foo.c
 bar.txt
 baz.c

And foo.c is: Copyright 2005 Some Company A
bar.txt is Copyright 2002 Some Person B
baz.c is Copyright 2002-2007 Other Fictional Entity

How would we represent such a case? Would we need to unpack that
tarball and then reference the files appropriately?

I have come across this case in Module::CPANTS::Analyse, which is a
Perl module that looks inside .tar.gz files without extracting them
out. It includes several such tarballs as a way to test the module
functionality.

Cheers,

Jonathan
