Subject Re: [GSoC] GUI for jar tool
Date Fri, 10 Apr 2009 01:19:05 GMT
Hi,

The purpose was to send you more detailed description of the additional 
GUI tool and to hear your comments on it:) I have already applied for 
jar tool and it is rather too late to send application for another one.

Cheers,
Tomek
