Apache::ReadConfig and RewriteRule

Hi, 
I am trying to setup some rules using Apache::ReadConfig (to setup 
Apache config using mod_perl) and was wondering how am I supposed to 
define the RewriteCond and RewriteRule entries. 

I would like to implement something similar to the following inside a VirtualHost.

RewriteEngine on
RewriteRule ^/$ /frontpage [R=permanent]
RewriteCond '%{HTTP_USER_AGENT} "MSIE 7.0; Windows NT 6.1"
RewriteRule ^(.*)$ http://pbcweb:8089$1 [L]

Primarily the issue I am facing is to figure out how to associate the 
RewriteCond with the RewriteRule. I can create an array of arrayref to 
enable all the RewriteRule though I am not sure where the RewriteCond for a particular RewriteRule would fit. I am assuming they will be some sort of array of hash refs but I 
couldn't find any example of how these arrays are to be structured. 

I would be appreciate it if someone could point me in the right direction.
