"Change Set: StandardFileStream-buffering Date: 30 August 2001 Author: Leandro Caniglia
Adds dynamic buffering support to StandardFileStream and subclasses. Files can be buffered and unbuffered on the fly. The buffer size of a file can change dynamically. New instances automatically born buffered or unbuffered, depending on a class setting (see StandardFileStream class >> instancesAreBuffered)" !
