Read up on the parent project here
OK... if you've arrived here, you're out on the bleeding edge. The idea with this repo (which is basically just freshly extracted from the sqlite_gui bit of FrozenGeek/OpenRVDAS) is that you install openrvdas from oceandatatools, then somewhere else you install this. Then you create a symlink in the top level openrvdas directory pointing to this directory.
Am I explaining that right? I'll work on that. For now, I'm going to try using this with a clean install. And for now, you probably shouldn't be trying to use this. But if you're interested, keep an eye on this project (and this README file).
