+searching DNA sequence databases for RNA structure and sequence similarities.
+It is an implementation of a special case of profile stochastic context-free
+grammars called @dfn{covariance models} (CMs).  A CM is like a sequence
+profile, but it scores a combination of sequence consensus and RNA secondary
+structure consensus, so in many cases, it is more capable of identifying RNA
+homologs that conserve their secondary structure more than their primary
+sequence.")
