The program has both graphical user interface (GUI) and command-line interface with 7 different compression modes:

nz_lzpf, a fast LZP compression
nz_lzpf_large, similar to nz_lzpf with a large window
nz_lzhd, a simplified nz_lzhds for extra speed
nz_lzhds, LZ variant designed for maximum speed
nz_optimum1, a modified nz_optimum2 for extra speed
nz_optimum2, BWT and an LZ variant
nz_cm, a CM compression mode

(Have info that should be added here? E-mail.)

The reason 0.07a -cf and -cF compression times are slower than 0.06a is because the program uses an additional thread while accessing harddisk, which causes disk IO time to be included into the total times.
