title: Environment-specific StructureMap configuration?
body: <p>Back when I used StructureMap 2.6, I was able to have it pull configuration data from a config by setting <code>PullConfigurationFromAppConfig</code> to TRUE. This was helpful for allowing me to override instances depending on the build configuration. </p>
  
  <p>In the newest version, this appears to be no more. How can I go about specifying custom instances via a configuration file, specifically the <code>web.config</code> (where I am currently doing transforms based on build config). Is this possible? Is there another IoC framework that DOES support this? Thanks.</p>
