The Yeha project is started to develop locales for East African languages. Many or most of which do not have ISO-639 Alpha 2 codes. Nonetheless locale data will be collected here and sample implementations offered that are compatible with glibc-2.2.

Why the name ``Yeha''? Viewing locales as a "foundation layer" for language support on an operating system the project leader looked for a term that embodied the "foundation" idea. Yeha in brief is the largest surviving structure from ancient times in the East African region and seemed a good choice. For some historical perspective on the original Yeha visit the article by Dr Pankhurst and the article by John Graham.
