Rule (Golly)

The "Rule" format is used by the program Golly to specify rules of cellular automata, as well as their visual appearance. It consists of one multi-section file, with the extension ".rule"; however, old (pre-2013 ) versions split up each of what became sections into their own files, with the extensions ".table", ".tree", ".colors", and ".icons", the most important being .table and .tree.

Identification
The current rule format starts with ASCII.
