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