+correlation/covariation in multiple sequence alignments and in side chain
+motions during molecular dynamics simulations.  Features include the
+computation of correlation/covariation scores using a variety of scoring
+functions between either sequence positions in alignments or side chain
+dihedral angles in molecular dynamics simulations and utilities to analyze the
+correlation/covariation matrix through a variety of tools including network
+representation and principal components analysis.  In addition, several
+utility functions are based on the R graphical environment to provide friendly
+tools for help in data interpretation.")
