Slim! is a powerful experimental compression utility, bundled with basic archiving functionality. Its primary purpose is to achieve maximum possible compression level, disregarding compression speed and memory requirements. Early Slim! versions use PPM* compression method, version 0.021 is probably the best PPM* implementation if judged by compression ratio. Since version 0.22 Slim! uses the progressive PPMII core, developed by Dmitry Shkarin.
