I need to find a way to add a css class to alternating children (much  
like the “cycle” helper in regular rails apps), and after looking at  
page\_context.rb it seems to me that the natural way to do this would  
be to extend the “children:each” tag like:

\<r:children:each css=“one\_class, two\_class”\>

where the the comma separated css values are applied to alternating  
children.

What I can’t seem to figure out is:

1. Is it possible to alter page\_context.rb, save the file, and then  
dynamically reload it without having to stop/restart the server?

2. How does one go about creating a new tag to handle the new css  
class feature? For instance, each child has a corresponding \<r:title  
/\> tag, how do I go about creating a \<r:css /\> tag? Or, is this the  
wrong way to do things entirely?

Any help would be greatly appreciated!
