+    (description
+     "Gene Set Variation Analysis (GSVA) is a non-parametric, unsupervised
+method for estimating variation of gene set enrichment through the samples of
+a expression data set.  GSVA performs a change in coordinate systems,
+transforming the data from a gene by sample matrix to a gene-set by sample
+matrix, thereby allowing the evaluation of pathway enrichment for each sample.
+This new matrix of GSVA enrichment scores facilitates applying standard
+analytical methods like functional enrichment, survival analysis, clustering,
+CNV-pathway analysis or cross-tissue pathway analysis, in a pathway-centric
+manner.")
