This is my bad for not asking in a previous CL, but why are the naming
conventions different here?

[Kyle Horimoto, 2017/04/20 02:16:08]

Shill constants are all in the "<UppercaseDeviceStateType>.<UppercaseProperty>"
format, and the device paths/names don't have readable names, so I just chose
the "tether-device-path" naming convention. It really doesn't matter what the
non-Shill values are as long as they are constants.

I was sure you were following a convention, was just curious. Thanks!
