Re: about "plot" + OT instruction for submitting help requests

[Shai Ayal]

tom,

If you want help you should provide some more info. At the minimum
please provide: Your OS, your octave version, how you got it (rpm,
source, ...)

A general remark:
when octave starts it gives a message stating:
"Report bugs to <address@hidden> (but first, please read
http://www.octave.org/bugs.html to learn how to write a helpful report)."

Maybe something similar should be said about the help list in this
context? Is there another place that instructions for a "good" way to
ask for help can be put, to be as visible as possible to people asking
for help?
