LRZIP is a compression program that can achieve very high compression ratios and speed when used with large files. It uses the combined compression algorithms of zpaq and lzma for maximum compression, lzo for maximum speed, and the long range redundancy reduction of rzip. It is designed to scale with increases with RAM size, improving compression further. A choice of either size or speed optimizations allows for either better compression than even lzma can provide, or better speed than gzip, but with bzip2 sized compression levels.
Changes: An lrztar wrapper was added for compressing and decompressing whole directories. An -i option was added to provide information about a compressed file. A "nan" showing as Compression speed on very small files was fixed. Building of the old bz library was fixed. The program now avoids overwriting the output file if the input doesn’t exist. A signal handler was implemented for deleting temporary files.
