-    i18n support. <!-- nice intro needed :) -->
+    I18n (short for internationalization) are means of adapting an application
+    for different languages and cultures. The scope of i18n support includes
+    support for local date and time, currency, measures, number formatting and
+    strings in different encoding. Native support for i18n and l10n 
+    (localization) appeared in PHP6.

+    Please note that in PHP6, POSIX locales are obsoleted by the set of locales 
+    included with the ICU library.
