O-K, Oberon Kompiler :)

O-K is an open source project to develop Oberon Language compiler.
Compiler should support at least Oberon, Oberon-2, and Oberon-SA language dialects.
It is in early stage of development now.

I don't think it is reasonable to download compiler now.
It is not ready for work yet
