+The Rc Template Language
+========================
+
+Implemented by Kris, thanks!
+
+Basic syntax:
+
+* Lines starting with % are executed as rc commands, the resulting output is inserted in the document.
+* use %{ and %} to delimit multi line sections of rc code (note the lack of space between % and { or }!
+* To 'inline' the value of an environment variable use `%($my_var%)`
+
+That is basically it!
+
+For further documentation on rc see:
+
+* [The rc(1) man page for Plan 9](http://man.cat-v.org/plan_9/1/rc).
+* [The rc shell paper by Tom Duff](http://rc.cat-v.org).
+
+
+Examples
+--------
+
+Loops
+
+    <ul>
+    % for(i in a b c) {
+    %   echo '<li>'$i'</li>'
+    % }
+    </uL>
+ 
+Is equivalent to: 
+
+    <ul>
+    % for(i in a b c) {
+    <li>%($i%)</li>
+    % }
+    </uL>
+
+and results in this output:
+
+    <ul>
+    <li>a</li>
+    <li>b</li>
+    <li>c</li>
+    </ul>
