Python usually, as far as I can tell. Either language is fine, I just think these things should be done in something that comes pre-installed on more systems.
I mean, I knew Chris years ago and his language of choice was Ruby, and I don't think it's changed.
Sure basic install-ability is great, but I bet you this tool was made to satiate an itch he had, and he used the tools he's used to. Little apps like these aren't engineered. Just hacks, for hacks sake.
