The primary goal is to swap command and option.

The secondary goal is to remap Caps Lock to Control.

The tertiary goal is to share modifier keys across keyboards, so you can emacs with two keyboards.

The following instructions are good as of 2016-08-24, for OS X El Capitan 10.11.6.
  Mac OS Sierra broke Seil support; Seil instructs us to consider Karabiner Elements.
  But when Karabiner Elements swaps command and option, it does it for all keyboards;
  meaning the native keyboard also gets its command and option swapped, which is bad!

Under 10.15.7, I woke my MacBook Pro from sleep to find the wifi constantly disconnecting and reconnecting, on a 20 second cycle.

I"m leaving this here in case anybody else finds it useful while troubleshooting.

Once it goes through, I'm gonna reboot.
