VisualOberon (or short 'VO') is a collection of classes written in the programming language Oberon-2. The classes are designed to easily build graphical user interfaces for programs written in Oberon-2. VO is distributed under the GNU license and it uses OO2C as development tool. Proposed package name will be "voberon", as "vo" is too short and likely to be confused/collide with other names.
