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