[Cin] Documentation on the EDL format

Hi, I have been working on <https://github.com/benfmiller/audalign> today regarding the "audio alignment problem". My goal is now to provide the clips as intermediate format EDL for Cinelerra, so the problem can be resolved outside first. The current EDL format "looks like XML" but certainly is not (for example attribute tags miss quotes etc.). Is there any documentation available on the EDL format itself? -- Stefan
