Hello,

I saw the full name of Matz, ruby creater, on the web [1]. However, I
don't know what is family name in his full name. AFAIK, CIA uses all
capital letters for family names because the factbook users are faced
with a world of different cultures and naming conventions [2].
Therefore, I suggest that the full name of Matz might be mark from
"Yukihiro Matsumoto" to "Yukihiro MATSUMOTO" if his family name is
"Matsumoto".

Sincerely,

Byung-Hee
