Hi, all.
I read this page about translating recently:
	http://www.netbsd.org/developers/translate.html

And I found such descriptions from it:
[...]
Note that the language-code (ISO639-1) may differ from the country-code
(ISO3166); Swedish is "sv" and is spoken in both Sweden, ("SE") and
Finland ("FI"). If you need to be more precise, use "language-country",
like "sv-se" for Swedish as spoken in Sweden, which might differ from
"sv-fi" - Swedish as spoken in Finland. See also the HTML4 language
specification.
[...]

According this rule. Do we need to change the directory name of the
'zh_TW' to 'zh-tw'?
(also 'pt' to 'pt-br'??)
