[arch-general] build and test packages automatically

[Guangyu Zhang]

Hello,

I want to build an repository. I need a software to build and test packages
automatically, and to show the status of all packages which is just like
the buildd <http://www.debian.org/devel/buildd/> in Debian. I have been
looking for it via Google, but nothing found.

Can anybody give me some advice? I also wonder what software is used by
official developers to manage the main repository.

Thanks,

Guangyu
