+
+This tool performs three basic calculations: 
+
+(1) Computes the number of heterozygotes
+(2) Computes the ratio between heterozygotes and homozygotes
+(3) Computes the total number of alleles in the input dataset
+
+----
+
+This tools is based on vcfhetcount, vcfhethomratio,and vcfcountalleles utilities from the VCFlib toolkit developed by Erik Garrison (https://github.com/ekg/vcflib).
