This is a C port of the google snappy compressor (http://code.google.com/p/snappy/) The compressor is very fast with reasonable compression ratio. It is mainly useful for projects that cannot integrate C++ code, but want snappy. Also contains a command line tool, a benchmark, random test code and a fuzz tester.
The compression code supports scather-gather and linear buffers. The scather gather code is ifdefed (-DSG) and can be removed with unifdef.

Requires the kerneldoc script from a Linux kernel source (may need to point the makefile to it). If you don't have the kernel source lying around just download it from https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/plain/scripts/kernel-doc and point the Makefile to it.
