The thing near the bottom of the buffer is how the environment
settings will be included in the mail. Please do not delete that.
They will tell the Bug People what your environment is, so that it
will be easier to locate the bugs.
If you have found a bug that makes Emacs go \"beep\", set
debug-on-error to t (`M-x set-variable RET debug-on-error RET t RET')
and include the backtrace in your bug report.
Please describe the bug in annoying, painstaking detail.
Thank you for your help in stamping out bugs.
