I see. I incorrectly assumed that \addEdition declares a set of edition-mods, 
but it makes much more sense that it applies them. Thanks for clarifying.

With the piece I'm currently working, on I'm attempting something similar using 
a bash script that iterates through every paper/tablet size, constructs \paper, 
prepends \version, appends \score, and tells lilypond to compile. Now I can 
also have it include a file containing the appropriate \addEdition statements.

Thanks for creating this very valuable tool. Lilypond is already far more 
powerful than any other scorewriter, but edition-engraver takes it to a whole 
other level.
