-     "GRIT is designed to use RNA-seq, TES, and TSS data to build and quantify
-full length transcript models.  When none of these data sources are available,
-GRIT can be run by providing a candidate set of TES or TSS sites.  In
-addition, GRIT can merge in reference junctions and gene boundaries.  GRIT can
-also be run in quantification mode, where it uses a provided GTF file and just
-estimates transcript expression.")
