Detailed Description
Portable random number generator class.
The reason for using this class if that you may want a consistent random number generator across all platforms supported by Crystal Space. Besides, in general it is a better quality RNG than the one supplied in most C runtime libraries. Personally I observed a significant improvement in a random terrain generator I made after I switched to this RNG.
