1487 At the bottom of the buffer you'll see lots of variable settings.
1488 Please do not delete those. They will tell the Bug People what your
1489 environment is, so that it will be easier to locate the bugs.
1491 If you have found a bug that makes Emacs go \"beep\", set
1492 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
1493 and include the backtrace in your bug report.
1495 Please describe the bug in annoying, painstaking detail.
