[M3devel] config file issue

[jay.krell at cornell.edu]

Agreed backup and always update. I don't want to consider merging.  
These are more code than data, but a mix.
(code is data...the CPU is an interpreter...)
I would like to aim for not needing user edits but that may be  
impossible to achieve.
