Replaygain's "smart" switch

[drmrbrewer]

If I leave off the "smart" switch in the replaygain command line, does this have the effect of processing all selected files as if they had not been replaygained before, overwriting any existing replaygain information and writing replaygain information where there is none?

That is indeed what I would like to happen. There are times where I'd like to add a track or two to an existing album folder, and hence I need to replaygain the whole folder again to ensure the album-based replaygain information is correct.

I did a google and forum search, but didn't find the answer (I found the question, but no-one had the answer!).

Thanks,

Mike
