repository layout:

dists
        stable
                main
                        arch #binary-arm fex
                        source #?
                contrib #?
                        arch # binary-arm fex
                        source
                non-free # guess.
                        arch
                        source
        testing...
        unstable...

arch/binary-* dirs hold Packages.gz, and Release (potentially) source dirs hold Sources.gz and Release (optionally)
