building a ports test server

[Benjamin Adams]

I'm trying to build a server that will do port build testing (amd64 system)

Steps:
1)download current ports
2)auto pick port to install
3) log all ports that are installed
4) when build is done and 100% with no errors
5) uninstall all ports installed (that where needed to get back to
default install)

Continue on to the next port

If build has and error write it to a test file for review later.

I'm trying to build a system that will do this.  Anyone know any
documentation for doing this?

Thanks,
