Fwd: New free update for DPGraph 2000 (Not an advertisement)

 Ok, below is an advertisement, I got. I did not forward it to this 
list in order to cash in since I have no relation whatsoever to this 
guy. This mail is more like spam, but good spam for once.

 This little piece of software is what I'd love to have under Gnome.
 I am already working on a math environment, and trying to learn from 
a 2D plotting widget called gtkplot to do nifty stuff and add plotting 
to it.

 I just want you to have a look at this! At what it does!

 Now if you are interested in trying to get something as close as this 
then you can count on me.

 The math project's page, I am working, is


 I have it on CVS already at sourceforge.com.

 And by the way, this is NOT in competition with Dr genius. For now it 
has a NumPy session, but I plan as soon as I can allow people to have 
(through MDI and maybe bonobo) multiple sessions, one for NumPy, one 
for plotting, one for genius ( and drag and drop from one to the 

 The advertising below is only meant to wet my appetite and other 
interested people appetites.

 Heck, this thing looks awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 We'd better start coding state-of-the-art stuff for Gnome!

 Thanx for reading until now
