Anyone here have any experience using the deployment agent from Halo?

It's supposed to give apt-live functionality to SMW; a command-line tool for downloading, installing, and upgrading SMWHalo extensions.

Just curious, because (some of) the extensions I've installed using this tool aren't showing up under Special:Version, and some of the code I'm getting from there is giving me "unsupported operand type" errors, from attempts to use '+' to add to arrays.

is this tool really ready for "prime time"?
I guess I'm back to the zip downloads...
