I don't use it. I am stuck on Pov 3·6.

But since "The syntax and effect are virtually identical to ambient".

Use it the way you would with ambient to add a bit of lighting. You can

Sorry, it is years since I looked at it and even then it was as a plugin.

I would be tempted to load the file(s) in a spreadsheet and filter it on 
ambient and emission. Just to see how often they are referenced. It 
might be a simple find & replace, job.
