If you have Octave working at all, the easiest way to prepare a complete
bug report is to use the Octave function bug_report. When you
execute this function, Octave will prompt you for a subject and then
invoke the editor on a file that already contains all the configuration
information. When you exit the editor, Octave will mail the bug report
for you.
If for some reason you cannot use Octave's bug_report function,
send bug reports for Octave to bug@octave.org.
Do not send bug reports to help-octave. Most users of Octave do not want to receive bug reports. Those that do have asked to be on the mailing list.
