Currently Swift modules are mostly consumed using semantic versioning (i.e. using SPM or Cocoapods).
This scheme is a revised version of semantic versioning that links the major version of the latest Swift toolchain that the
MAJOR - Incremented when the project is updated to a new Swift language version. e.g. For Swift 4, this would be '4'.

| // Reggie added, simple gpio keys polled driver, adds button support via gpio | |
| // will be useful for embedded devices, see gpio-mouse, gpio-fan and rotary-encoder | |
| // for other examples of gpio access to devices from the linux kernel | |
| // this will use GPIO4,17,21,22 as a simple test, they will be set to active_low | |
| // so should have a pullup added to each pin and button tied to ground. | |
| // We have to use polled at the moment because the current kernel doesn't have | |
| // code to handle an interrupt driven gpio-keys driver, which would've been much nicer | |
| // you should check the wiki to make sure that these gpio are correctly configured | |
| // and see whether they are physically pulled up on the schematic, if they're not | |
| // add a 10k pullup to the gpio-keys pins and tie the button to gnd |
