1475 At the bottom of the buffer you'll see lots of variable settings.
1476 Please do not delete those. They will tell the Bug People what your
1477 environment is, so that it will be easier to locate the bugs.
1479 If you have found a bug that makes Emacs go \"beep\", set
1480 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
1481 and include the backtrace in your bug report.
1483 Please describe the bug in annoying, painstaking detail.
