+     "The package offers functions for analyzing and interactively exploring
+large-scale single-cell RNA-seq datasets.  Pagoda2 primarily performs
+normalization and differential gene expression analysis, with an interactive
+application for exploring single-cell RNA-seq datasets.  It performs basic
+tasks such as cell size normalization, gene variance normalization, and can be
+used to identify subpopulations and run differential expression within
+individual samples.  pagoda2 was written to rapidly process modern large-scale
+scRNAseq datasets of approximately 1e6 cells.  The companion web application
+allows users to explore which gene expression patterns form the different
+subpopulations within your data.  The package also serves as the primary
+method for preprocessing data for conos.")
