Send config variable to index.php?

Thanks Colin. That would work but the config file is in the "ver_".$app_version."/app/config" path, so it would never be able to find itself. This same variable would be reused to locate the correct version of the asset folder from my template, view file as well. Here's my layout:

sys_1.7.2
ver_1.0.1
--app
--assets
ver_1.0.2
--app
--assets

So basically it's a var that can be grabbed at any time from any controller or view. Am i going about this all wrong perhaps?
