There's also Meteorite (<a href="http://oortcloud.github.com/meteorite/" rel="nofollow">http://oortcloud.github.com/meteorite/</a>), which does a bit more by offering more Smart Packages via Atmosphere (<a href="https://atmosphere.meteor.com/" rel="nofollow">https://atmosphere.meteor.com/</a>).
I found this in the .sh file: export SSH_HOST=root@$APP_HOST<p>So it seems to try to log into root@your.server. Which seems like a terrible idea.<p>Also it uses a lot of apt-get, so I guess you are limited to linux.
