NAME

       octave-bug - report a bug in GNU Octave

SYNOPSIS

       octave-bug [-s subject]

DESCRIPTION

       octave-bug is a shell script to help the user compose and mail bug reports concerning Octave in a standard format.  octave-bug is typically
       invoked by the Octave command bug_report which is intended to be called interactively from within Octave. This provides	the  best  way	to
       submit  a  bug  report for Octave. It creates a template bug report file and starts an editor on that file.  The bug report will be sent to
       the bug-octave mailing list once the editing has been completed (this assumes of course that your system can use email). However, the  user
       could also call octave-bug outside of Octave.

       Please  read  the `Bugs' chapter in the Octave manual to find out how to submit a bug report that will enable the Octave maintainers to fix
       the  problem.   If  you	are  unable  to  use  the  bug_report  command,  send  your  message  to  the  bug-octave   mailing   list,   bug-
       octave@bevo.che.wisc.edu.

OPTIONS

       -s subject
	      Specify a subject line for the bug report.  Spaces in the subject must be quoted.

ENVIRONMENT VARIABLES

       octave-bug uses the environment variables USER, EDITOR, and PAGER which can be used for customization.

VERSION

       This document was last revised for Octave version 2.0.16.
