Hi all,

Ruby includes zlib library, but I cannot find a mention about zlib in the LEGAL file[1]
even though zlib is probably licensed under zlib license as it is probably mentioned
by the Japanese Ruby license wiki page[2].

That makes me confused. Under what license is zlib in Ruby included?

Thank you.

No code from zlib (http://www.zlib.net) is included in ruby, only a wrapper for the zlib library (loaded by require 'zlib'). This wrapper needs no separate license information.

Per note 2, google translate indicates this is an explanation of how the license applies to software and does not indicate that ruby contains any zlib code.
