&lt;br /&gt;
'''RLE''' is a format used for storing patterns of cellular automata. As the name suggests, it uses [[run-length encoding]]. It was designed by [https://www.conwaylife.com/wiki/David_Buckingham David Buckingham].&amp;lt;ref&amp;gt;http://golly.sourceforge.net/Help/formats.html#rle&amp;lt;/ref&amp;gt; The program Golly uses a derivative format called [[Extended RLE]].&lt;br /&gt;
&lt;br /&gt;
== Identification ==&lt;br /&gt;
Standard RLE files will begin with [[ASCII]] &amp;quot;{{magic|1=x =}}&amp;quot;&amp;lt;!-- It begins with &amp;quot;x =&amp;quot;. The &amp;quot;1=&amp;quot; is required so that the magic number won't be interpreted as template markup.--&amp;gt;.&amp;lt;ref&amp;gt;http://www.mirekw.com/ca/ca_files_formats.html#RLE&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Specifications ==&lt;br /&gt;
* [http://www.mirekw.com/ca/ca_files_formats.html#RLE Unofficial specification]&lt;br /&gt;
&lt;br /&gt;
== Software ==&lt;br /&gt;
RLE seems to be very widely-supported; therefore, a list of programs supporting it would almost amount to a list of all CA software.&lt;br /&gt;
