  73 <p>
  74       Boost.Accumulators is both a library for incremental statistical computation
  75       as well as an extensible framework for incremental calculation in general.
  76       The library deals primarily with the concept of an <span class="emphasis"><em>accumulator</em></span>,
  77       which is a primitive computational entity that accepts data one sample at a
  78       time and maintains some internal state. These accumulators may offload some
  79       of their computations on other accumulators, on which they depend. Accumulators
  80       are grouped within an <span class="emphasis"><em>accumulator set</em></span>. Boost.Accumulators
  81       resolves the inter-dependencies between accumulators in a set and ensures that
  82       accumulators are processed in the proper order.
