How to Validate a GeoJSON

I have a small script that I'm using to generate GeoJSON data from a data format not currently supported by GIS software.

I would like to validate the output, but when I use ogr2ogr to read it, it doesn't give me any helpful information about what aspects, lines, or characters contained invalid data.

Is there a decent GeoJSON validator somewhere, or a good method of validating GeoJSON data with OGR?

EDIT: I am not looking for JSON validators or the GeoJSON spec. I've seen and used both to get to this point, but OGR still returns an error.

Thanks!
