191 The thing near the bottom of the buffer is how the environment
192 settings will be included in the mail. Please do not delete that.
193 They will tell the Bug People what your environment is, so that it
194 will be easier to locate the bugs.
196 If you have found a bug that makes Emacs go \"beep\", set
197 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
198 and include the backtrace in your bug report.
