Is there an event available for whenever the File Sumary is edited, either when a new file is uploaded, or when it's edited "in place" (without uploading a new file).

I have capture the FileCheckedIn event, and I can get to the Summary from there, and it works fine.  However, if they upload a new version, or just edit the FileSummary, I can't seem to capture that.

Does anyone have any ideas on how to capture this event?
