hi everyone. I am willing to participate in
GSOC 2015 and interested in GED Transactions projects. where can I
find previous bugs in your project so that I can fix one or two.
Moreover where can I find your source code repository? I have
checked almost every relevant link. Any help would be highly
appreciated. Thank you. |
