A library for building self-adjusting computations, following the work of Umut Acar et. al.. Incremental gives you a way of building complex computations that can update efficiently in response to their inputs. Incremental can be useful in a number of applications, including:

• Building large calculations (of the kind you might build into a spreadsheet) that can react efficiently to changing data.
• Constructing views in GUI applications that can incorporate new data efficiently.
• Building online versions of existing combinatorial algorithms.

You can find detailed documentation in of the library and how to use it in incremental_kernel/src/incremental_intf.ml. You can also find an informal introduction to the library in this blog post.
