+     "PRANK is a probabilistic multiple sequence alignment program for DNA,
+codon and amino-acid sequences.  It is based on a novel algorithm that treats
+insertions correctly and avoids over-estimation of the number of deletion
+events.  In addition, PRANK borrows ideas from maximum likelihood methods used
+in phylogenetics and correctly takes into account the evolutionary distances
+between sequences.  Lastly, PRANK allows for defining a potential structure
+for sequences to be aligned and then, simultaneously with the alignment,
+predicts the locations of structural units in the sequences.")
