+     "The anota2seq package provides analysis of translational efficiency and
+differential expression analysis for polysome-profiling and ribosome-profiling
+studies (two or more sample classes) quantified by RNA sequencing or
+DNA-microarray.  Polysome-profiling and ribosome-profiling typically generate
+data for two RNA sources, translated mRNA and total mRNA.  Analysis of
+differential expression is used to estimate changes within each RNA source.
+Analysis of translational efficiency aims to identify changes in translation
+efficiency leading to altered protein levels that are independent of total
+mRNA levels or buffering, a mechanism regulating translational efficiency so
+that protein levels remain constant despite fluctuating total mRNA levels.")
