# CHOOSE A VERSION

 This script will help you choose a version of Libreoffice, because they are
 classified according to functionality (STILL and FRESH) and the number of 
 languages included (STANDARD and FULL):
 
 - STILL is the Stable version. This version is slightly older and does not 
   have the latest features, but it has been tested for longer.

   adopter or power user, this version is for you!
 - STANDARD supports English (US and GB), Arabic, Chinese (Simplified and 
   Traditional), French, German, Italian, Japanese, Korean, Portuguese 
   (Brazilian and Portugal), Russian, and Spanish.
 - FULL includes all the languages supported by LibreOffice.
