Ruby computational geometry library. Shape/Line/Point classes, methods to test shape intersection (using ray-casting algorithm); includes XML parsing script (& sample xml file) to test intersection of shapes documented as ordinal point set in xml.
It is an experimental project developed for synchronization of folders with a FTP server. It was developed when dropbox, sugarsync werent hit ;)
It can be studied for using ruby for such purpose. Not in shape for using it for practical purpose.
