356 I'm very sorry. It seems that an error occurred in Sup. Please
357 accept my sincere apologies. If you don't mind, please send the
358 contents of ~/.sup/exception-log.txt and a brief report of the
359 circumstances to sup-talk at rubyforge dot orgs so that I might
360 address this problem. Thank you!
