+perform a range of basic, large-scale analyses in a computationally efficient
+manner.  The focus of PLINK is purely on analysis of genotype/phenotype data,
+so there is no support for steps prior to this (e.g. study design and
+planning, generating genotype or CNV calls from raw data).  Through
+integration with gPLINK and Haploview, there is some support for the
+subsequent visualization, annotation and storage of results.")
