Good point, actually I never think about this way before, maybe this
is a good way for Gnu ELPA. git access to savannah is very slow (< 50
KiB/s) and unreliable here, I will try this way after (if) git-clone
is done. Also, I am not sure if building locally can keep old versions
of packages like GNU ELPA.

Anyway, I still think rsync is the best way to mirror.

MELPA itself needs 3 hours to build its 3000+ packages. Building MELPA
packages locally is not easy.

I am not very sure if we are ruining the download statistics, but the
user-agent we used is always different from Emacs/url.el/package.el
