.SH NAME
D__seq_rptn \- Interface for class D__seq_rptn

.SH DESCRIPTION
D__seq_rptn is a class template used to define sequential repetition
classes.  D__seq_rptn is defined as an abstract class template, which
means its methods are not fully implemented. To define a sequential
repetition class, a user must inherit from an instantiation of one of
the concrete subclasses of D__seq_rptn, e.g., D__linked_list.

Assuming template<class R> class D__seq_rptn, the following methods
are available to users of class D__seq_rptn.
