(To Joao Cardoso & Rafael Laboissiere and P.J.G. Long) graceplot package problem

[Tatsuro MATSUOKA]

Dear Joao Cardoso & Rafael Laboissiere

P.J.G. Long and I have been discussed the graceplot problem in address@hidden
I'm mere a cygwin maintainer and the cygwin in my home computer is not in good 
condition I have not
been able to execute Grace even it is certainly installed in my cygwin directry 
trees.
Therefore I cannot help for P.J.G. Long any more.
(Now I have complete delete my cygwin (including its registry keys) and now 
re-installing now.)


The topic seems to be a graceplot problem not but the octave itself.
I think that it is better to move to address@hidden

Dear P.J.G. Long

If you have not still subscribe to the address@hidden,
please subscribe the first:

https://lists.sourceforge.net/lists/listinfo/octave-dev

The ML discussions until now can be seen here:
http://www.nabble.com/Problems-compiling-qtoctave-0.7.1-to15234197.html#a15360078

Unfortunately this topic seems to be mixed in the other topic of the qtoctave,
please see only for 'Octave Forge functions in 3.0.0'.

Thank you in advance for your kind cooperation.

Regards

Tatsuro
