DJP is a fast and small executable file compressor for files produced by DJGPP V2. It uses an algorithm called LZO1X, which achieves an average compression ratio of about 0.56 on executable files, and can decompress at about 6-8 Mbytes/sec on an AMD 486DX4-100 with no memory
overhead. (Decompression speed is defined as uncompressed size/decompression time.)
