Applied, thanks (I tweaked the indenting slightly).

Right. I think the order's how things used to be in Portage back when
we made the list. It'd probably look nicer as a table, something like:

    Extension     EAPIs          Must have installed
                  1 2 3
    .tar.gz       y y y          GNU tar, GNU gzip
    .tar.lzma         y          LZMA Utils

That's an 'easy' exercise for someone who feels like being helpful...

Incidentally, one of the things I was hoping to get in for EAPI 4 was a
fix for the arbitrary and weird dependencies required for unpacking. I
think we briefly discussed doing something like making the package
manager have 'magic' packages, so you'd do:

    DEPEND="package-manager-magic/unpack-zip"

to tell the package manager to depend upon whatever it really uses to
unzip things. I don't recall whether this was feasible from a Portage
perspective though.
