%description
This package is a playground full of comonadic folds.
This style of fold is documented in
<https://www.fpcomplete.com/user/edwardk/cellular-automata/part-2 "Cellular
Automata, Part II: PNGs and Moore">
This package can be seen as what happens if you chase Max Rabkin's
<http://squing.blogspot.com/2008/11/beautiful-folding.html "Beautiful Folding">
to its logical conclusion.
More information on this approach can be found in the
