`module Make : functor (Incr : Incremental_kernel.Incremental_intf.S) -> sig ... end`

This module provides the ability to create a large set of incremental outputs based on a single incremental input, where some subset of the outputs are selected to have specific values, and the remainder are left with a specified default value. The outputs are updated in time proportional to the number of outputs that are changed, independent of the number of outputs that exist. Each function returns a staged function for allocating new output incrementals.
