title: Purpose of /var/resource_config.json
body: <p>I'm trying to figure out what the purpose of the file /var/resource_config.json is in Magento.  It appears to perhaps be a caching of a configuration, but can't see where in the source code it is being created and/or updated.</p>
  
  <p>I'm in the process of setting up local/dev/staging/prod environments for an EE1.12 build and want to figure out if I can safely exclude it from my repo or whether I need to script some updates to it for deploys.</p>
  
  <p>Maybe the flash image uploader in admin creates it?</p>
  
  <p>Any ideas or directions to look?</p>
