    z="Host: archive.netbsd.org"
    sed '$!s>.*>'"$y"'& HTTP/1.1[]'"$z"'[]Connection: keep-alive[]>;
         $s>.*>'"$y"'& HTTP/1.0[]'"$z"'[]>' << eof \
    |tr '[]' '\r\n' \
    |openssl s_client -quiet -connect 151.101.129.6:443 -servername archive.netbsd.org > http+gzip

    yy054 < http+gzip|tar tvzf /dev/stdin

Alternate usage:

Include an argv[1] will print HTTP headers only

    yy054 print < http+gzip
    yy054 x < http+gzip
