154 be sent to the Gnus Bug Exterminators.
156 The thing near the bottom of the buffer is how the environment
157 settings will be included in the mail. Please do not delete that.
158 They will tell the Bug People what your environment is, so that it
159 will be easier to locate the bugs.
161 If you have found a bug that makes Emacs go \"beep\", set
162 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
163 and include the backtrace in your bug report.
165 Please describe the bug in annoying, painstaking detail.
