+(This is related to #1262, which is not a bug, so, it should be a wiki entry. However, I can't attach files because Akismet thinks I'm a spammer. Someone please attach here the file that's attached to #1262).
+
+=== What is it? ===
+
+    * Attached is an adaptation of the port of RoR's JavascriptHelpers (http://pylonshq.com/project/pylons/browser/RailsHelpers) by Ben Bangert to Django tag library. 
+
+    * It also includes port of Eugene's LiveFilter?(dojo) to prototype (DelayedObserver in observer.js). 
+
+=== Usage ===
+
+{{{
+{% rails function_name (arg1,arg2,kwarg1=3,...) %}
+
+        or
+    
+{% rails function_name %}
+arg1,arg2,
+arg3,
+kwarg1=value1,
+kwarg2=value2,
+ ...
+{% endrails %}
+}}}
+
+=== Usage Examples ===
+
+{{{
+{% load railshelper %}
+
+{% rails link_to_function ("Greeing", "alert('Hello World')") %}
+
+{% rails link_to_remote %}
+"Delete this post", 
+{'update':"posts",'url':"./destroy"}
+{% endrails %}
+
+{% rails observe_form %}
+"searchform",
+url='?format=ahah', 
+update='results',
+delay=0.3,
+method='get',
+complete="SEL.setup('product_list');",
+{% endrails %}
+}}}
+
+=== Issues ===
+
+    * Used exec to do the parameter parsing. So people may not like it, but this was the quickest way I could think of. External parameter is exec-ed only within a function argument:
+
+{{{
+      def argparser(*args, **kws):
+          return args, kws
+      exec("args, kws=argparser("+param+")")
+}}}
+
+      I could not think of any malicious thing to do in function argument but probably there are many. Please let me know. 
+
+    * Easily modifiable to render passed parameter as django template. 
+    * Tested only "link_to_remote", "observe_form" in real web browser (IE, FF, Opera).
