+==============================
+Lzip data compression in Linux
+==============================
+
+Introduction
+============
+
+Lzip is a lossless data compressor with a user interface similar to the one
+of gzip or bzip2. Lzip uses a simplified form of the 'Lempel-Ziv-Markov
+chain-Algorithm' (LZMA) stream format, chosen to maximize safety and
+interoperability. Lzip can compress about as fast as gzip (lzip -0) or
+compress most files more than bzip2 (lzip -9). Decompression speed is
+intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from
+a data recovery perspective. Lzip has been designed, written, and tested
+with great care to replace gzip and bzip2 as the standard general-purpose
+compressed format for unix-like systems, especially for long-term archiving.
+
+Learn more about lzip at http://www.nongnu.org/lzip/lzip.html
+
+Lzip related components in the kernel
+=====================================
+
+The lzip_decompress module in lib/lzip_decompress.c provides a versatile lzip
+decompression function able to do buffer to buffer decompression or stream
+decompression with fill and flush callback functions. The usage of the
+function is documented in include/linux/lzip.h.
+
+For decompressing the kernel image, initramfs, and initrd, there is a wrapper
+function in lib/decompress_lunzip.c providing the same common interface as the
+other decompress_*.c files, which is defined in
+include/linux/decompress/generic.h.
+
+For kernel makefiles, two commands are provided in scripts/Makefile.lib for
+use with $(call if_changed). The kernel image must be compressed with
+$(call if_changed,klzip) which will append a four-byte trailer containing the
+size of the uncompressed data needed by the boot code. Other things should be
+compressed with $(call if_changed,lzip).
+
+Testing
+=======
+
+Lzip-compressed kernel images of multiple linux versions since 2.6.30.10 have
+been built and tested, even on machines as modest as an AMD 486-DX2 at 66 MHz
+with 64 MiB of RAM. In the worst case (on the slow machine above), lzip just
+increased the boot time a 15% compared with gzip. On more modern machines,
+lzip may boot slightly faster than gzip. It just takes 0.2 seconds for lzip to
+decompress vmlinuz-4.4.16 on my machine.
+
+Decompression time is usually a small fraction of the total boot time. For
+example, using lz4 on a desktop machine in order to save 0.05 seconds of a
+total boot time of 20 seconds is probably not worth the increased image size.
+
+Xlunzip is a test tool for the lzip_decompress module. It is similar to
+lunzip, but it uses the lzip_decompress module as a backend. The xlunzip home
+page is at http://www.nongnu.org/lzip/xlunzip.html
