125 The buffer below is a mail buffer. When you press `C-c C-c', it will

128 At the bottom of the buffer you'll see lots of variable settings.
129 Please do not delete those. They will tell the Bug People what your
130 environment is, so that it will be easier to locate the bugs.
132 If you have found a bug that makes Emacs go \"beep\", set
133 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
134 and include the backtrace in your bug report.
136 Please describe the bug in annoying, painstaking detail.
138 Thank you for your help in stamping out bugs.
