+
+    Seq-Gen is a program that will simulate the evolution of nucleotide or
+    amino acid sequences along a phylogeny, using common models of the
+    substitution process. A range of models of molecular evolution are implemented
+    including the general reversible model. State frequencies and other parameters
+    of the model may be given and site-specific rate heterogeneity may also be
+    incorporated in a number of ways. Any number of trees may be read in and the
+    program will produce any number of data sets for each tree. Thus large sets of
+    replicate simulations can be easily created. It has been designed to be a
+    general purpose simulator that incorporates most of the commonly used (and
+    computationally tractable) models of molecular sequence evolution."""
