126 ========================================
128 The buffer below is a mail buffer. When you press `C-c C-c', it will
129 be sent to the Gnus Bug Exterminators.
131 The thing near the bottom of the buffer is how the environment
132 settings will be included in the mail. Please do not delete that.
133 They will tell the Bug People what your environment is, so that it
134 will be easier to locate the bugs.
136 If you have found a bug that makes Emacs go \"beep\", set
137 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
138 and include the backtrace in your bug report.
140 Please describe the bug in annoying, painstaking detail.
142 Thank you for your help in stamping out bugs.
