download-release-error-hook #!optional ERROR-HOOKparameter

This is a hook you can register to run some code whenever a full release of an egg has failed to download.

ERROR-HOOK is a procedure of four arguments: the major CHICKEN release (an integer), the egg name, the release version and the error message on the exception that was thrown when the failure happened (the latter three are all strings).
