FYI, Info-ZIP (the common zip(1) on Linux, available for all major and many
minor OSs) can do this perfectly well:

    rm -f public.zip
    zip -0 public.zip art/badger.jpg art/mushroom.tif scripts/snake.py

or even

    rm -f public.zip
    cat > filelist.txt
    art/badger.jpg
    art/mushroom.tif
    scripts/snake.py
    ^D
    zip -0 public.zip -@ < filelist.txt

See the Debian packaging for openarena-data [1], which jumps through hoops to
keep files in the PK3 in the same order as distributed upstream so they don't
fail network-compatibility checksumming.
