I don't grok ruby but I've telling myself I should learn [sigh]. I don't know if this has a simple API or not; I'll take a look but I suspect it is probably overkill. If this doesn't meet your project's needs I'll try coding something up in C. I imagine we'll need some tools written in C at some point anyhow. > Thank you very much for the help :)! > Well, we'll see about how much help I can be; but I'll try.
