        	zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms.

            Sickle requires a C compiler; GCC or clang are recommended. Sickle relies on Heng Li's kseq.h, which is bundled with the source. It also requires zlib, which is included in this repo.
