+and perform accurate inference on differentially methylated regions from Whole
+Genome Bisulfite Sequencing data.  The method is based on comparing detected
+regions to a pooled null distribution, that can be implemented even when as
+few as two samples per population are available.  Region-level statistics are
+obtained by fitting a @dfn{generalized least squares} (GLS) regression model
+with a nested autoregressive correlated error structure for the effect of
+interest on transformed methylation proportions.")
