+
+This method is called after the config file is loaded. It can be
+used to implement tuning of config values that can only be done
+at runtime. If you need to do this to properly configure any
+plugins, it's important to load ConfigLoader before them.
+ConfigLoader provides a default finalize_config method which
+walks through the loaded config hash and replaces any strings
+beginning with C<< __HOME__/<path> >> with the full path to
+the file inside the app's home directory.
