いつの間にか Zopfli-1.0.0 が出てた
一ヶ月前のリリースに今更気付きました。(ツイッターで見たの忘れてただけかもですが)
git pull で表示される差分を見る限り、1.0.0 で入れたのは png 対応のようです。> 差分は最後の方に張り付けます。

zopflipng
yoya@sakura:~/git/zopfli$ make zopflipng
yoya@sakura:~/git/zopfli$ ./zopflipng -h | grep Usage -A 5
Usage: zopflipng [options]... infile.png outfile.png
zopflipng [options]... --prefix=[fileprefix] [files.png]...
If the output file exists, it is considered a result from a previous run and not overwritten if its filesize is smaller.
Options:
--
Usage examples:
Optimize a file and overwrite if smaller: zopflipng infile.png outfile.png
Compress more: zopflipng -m infile.png outfile.png
Optimize multiple files: zopflipng --prefix a.png b.png c.png
Compress really good and trying all filter strategies: zopflipng --iterations=500 --splitting=3 --filters=01234mepb --lossy_8bit --lossy_transparent infile.png outfile.png
