NOTE:
Azhagi+ has possessed the fastest of all Tamil transliteration schemes, ever since its inception in 2000. You can quickly extend Azhagi+ to transliterate in ANY Tamil font by using a never-before-seen feature. You can easily extend Azhagi+ to type in any 'Language + Font + Keyboard' combination by availing a very special feature. You can very well change the existing key mappings, avail a 'first of its kind' Tamil font encodings converter (extendable by the user to convert from ANY Tamil font to ANY other Tamil font), and do much more...
