Before anyone gets too involved in converting the the Varkon code comments to English, or another language, I think I would wait until we see if the libraries/application are usable, etc. Overall, the Varkon code is pretty clean and well organized. Not all the comments are in Swedish; there are some big blocks of English code. Some/most of the variable names and routines have Swedish encoding, things like "cru" for curve or circle, for instance. I wish the code was object orientated. I'm not that deep into it, but the hierarchy looks pretty loose, which might make it harder to figure out. Something like circle.centerpoint or circle.draw would be easier to interpret. However, beggars can't be choosers. I've got other comments, but no time to write them. Kim
