Subject Re: [PROPOSAL] jSpirit Project : English Presentation
Date Thu, 22 Jul 2010 17:17:04 GMT
Hi,

As requested, I add a presentation of jSpirit project on SF in English.

Here is the link [ 
https://sourceforge.net/projects/jspirit/files/doc/jspirit_presentation_en.pdf/download 
].

I apologize for my bad English, I hope it will be understandable.

Regards,

Grégoire
