132 ========================================
134 The buffer below is a mail buffer. When you press `C-c C-c', it will
135 be sent to the Gnus Bug Exterminators.
137 At the bottom of the buffer you'll see lots of variable settings.
138 Please do not delete those. They will tell the Bug People what your
139 environment is, so that it will be easier to locate the bugs.
141 If you have found a bug that makes Emacs go \"beep\", set
142 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
143 and include the backtrace in your bug report.
145 Please describe the bug in annoying, painstaking detail.
