[Samie Bee]

Wasatch.PY script (something that comes along with our PyPi package).

Note that some EEPROM utility functions are available in this “one-shot” (no dependencies, ergo redundant yet functionally complete):

It would not be hard to add a little --set “field:value” argument that would allow quick cmd-line setting of any value.
