[GNC] Writing GCM File

[David T.]

Adrien, 

My guess aligns with yours as to why the rewrite was taking place, although it isn't clear to me why GnuCash would rewrite *every* register entry. 

The readme that I wrote at the github page includes a long explanation of my experience, findings, and the script's procedures. I'm not in the wiki editing business any more, so I leave it to others to add or modify content there.

At least, that's what I'd expect to find should I read it. (and admittedly, have not — yet)
