= locale - locale for Ruby
Locale gem is the pure ruby library which provides basic and general
purpose APIs for localization.
This library was called as "Ruby-Locale". Since 2.0.6, this library is
called just "locale". You can call this library as "locale gem" or
"Ruby Locale" to distinguish from other "locale"s.
This library aims to support all environments which Ruby works and all
kind of programs (GUI, WWW, library, etc), and becomes the hub of
other i18n/l10n libs/apps to handle major locale ID standards.
* Manage Locale ID(Language Tag)
* Each thread has a Locale ID.
* POSIX, CLDR, IETF(RFC4646, 3066(BCP47)), Win32 and Java language tags
and convert the tag string to each other.
* Auto detect Locale ID.
POSIX(Unix/Linux/*BSD), Win32, JRuby, CGI(CGI, Rack, others).
* Resources
* ISO 639-3 languages
* ISO 3166 region(countries).
* Support Ruby 1.8.7, Ruby 1.9.1, JRuby 1.1.4. Tested on Win32 and Linux.
