1649 ========================================
1651 The buffer below is a mail buffer. When you press `C-c C-c', it will
1652 be sent to the Gnus Bug Exterminators.
1654 At the bottom of the buffer you'll see lots of variable settings.
1655 Please do not delete those. They will tell the Bug People what your
1656 environment is, so that it will be easier to locate the bugs.
1658 If you have found a bug that makes Emacs go \"beep\", set
1659 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
1660 and include the backtrace in your bug report.
1662 Please describe the bug in annoying, painstaking detail.
