[boost] missing locale/info.hpp

Hi in your documentation you mention the availability of info.hpp (located in /boost/locale) I've just downloaded the latest 1.47 release and there's no such "locale" subdirectory and no info.hpp file containing a <locale> include statement. I'd like to use the language settings provided with this header file. Where can it be found? Where can the corresponding library be found? Thanks for your feedback Markus
