142 Developers. (the addresses below are mailing list addresses)
144 ========================================
146 The buffer below is a mail buffer. When you press `C-c C-c', it will
147 be sent to the Gnus Bug Exterminators.
149 At the bottom of the buffer you'll see lots of variable settings.
150 Please do not delete those. They will tell the Bug People what your
151 environment is, so that it will be easier to locate the bugs.
153 If you have found a bug that makes Emacs go \"beep\", set
154 debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
155 and include the backtrace in your bug report.
157 Please describe the bug in annoying, painstaking detail.
159 Thank you for your help in stamping out bugs.
