             WHAT THIS OBJECT REPRESENTS
-                This object is a tool for doing sequence labeling.  In particular,
-                it is capable of representing sequence labeling models such as
-                those produced by Hidden Markov SVMs or Conditional Random fields.
-                See the following papers for an introduction to these techniques:
