Package for the new BCFtools: a set of utilities that manipulate variant calls in the Variant Call Format (VCF) and its binary counterpart BCF. It contains all the "vcf..." commands which previously lived in the HTSlib repository (such as vcfcheck, vcfmerge, vcfisec, etc.) and the samtools BCF calling from bcftools subdirectory of samtools. BCFtools are meant as a faster replacement for most of the perl VCFtools commands.
