&lt;br /&gt;
The &amp;quot;'''Rule'''&amp;quot; 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 &amp;quot;.rule&amp;quot;; however, old (pre-2013&amp;lt;ref&amp;gt;http://golly.sourceforge.net/Help/changes.html →  &amp;quot;Changes in version 2.5 (released June 2013)&amp;quot;&amp;lt;/ref&amp;gt;) versions split up each of what became sections into their own files, with the extensions &amp;quot;.table&amp;quot;, &amp;quot;.tree&amp;quot;, &amp;quot;.colors&amp;quot;, and &amp;quot;.icons&amp;quot;&amp;lt;ref&amp;gt;http://golly.sourceforge.net/Help/formats.html#deprecated&amp;lt;/ref&amp;gt;, the most important being .table and .tree.&lt;br /&gt;
&lt;br /&gt;
