This file should be saved into the "etc" directory, found under your Interchange installation's home directory.
Once saved, you should edit your "interchange.cfg" file to (1) add a line that reads "include etc/robots.cfg", and (2) to remove any existing "Robot*" and "NotRobot*" directives from your configuration.
Interchange 5.5.0 and above is supplied pre-configured to use "etc/robots.cfg", so you can simply replace this file with the latest version, every now and again, without having to edit your "interchange.cfg" file.
Note that changes to this file will not take effect until you restart Interchange.
