Do you know where can I find some information of this algorithm, to study it??. Is there already an example of its implementation, or, only Quinlan knows its implementation??

C5.0 which Quinlan is commercially selling is an improvement on C4.5.

According to this sentence from the wikipedia page this algorithm is not open for everyone. I guess it will take some effort to get something going by yourself.
