GSoC 2013 - Registry Merging Project

[orzhvs]

Hi Juan,
Thank you for your reply.
Sincerely sorry for my late application, you know that's really not
pleasing. But I think that increase my enthusiasm at the same time. I will
keep focus and spend more time on it as I'm just getting start in the
community.
I love it even more when it seems to be a challenge :)

regards.
Guo Jian
