-- app-eeprog.lua : Tiny EEPROM flasher
-- Authors: 20kdc

-- Example of a tiny app a user could write relatively quickly if they have NEO system knowledge
-- Note the high amount of synchronous routines used here.
-- For a tiny app like this, it's fine, and KittenOS NEO makes sure it won't interfere.
-- (Plus, this isn't a library, so that's not a concern)
-- Really, in KittenOS NEO, the only program you break is your own
