ENVIRONMENT:
  ESP8266_ARDUINO_SKETCHES - list of .ino files; defaults to **all available examples**
  ESP8266_ARDUINO_BUILDER - arduino or platformio

  For Arduino IDE:
    ESP8266_ARDUINO_IDE - path to the IDE (portable)
    ESP8266_ARDUINO_HARDWARE - path to the hardware directory (usually, containing our repo)
    ESP8266_ARDUINO_LIBRATIES - path to the libraries directory (external dependencies)
    ESP8266_ARDUINO_DEBUG - debug or nodebug
    ESP8266_ARDUINO_LWIP - v4 or v6

USAGE:
  $cmd <[even | odd]> - build every Nth, when '<N> % 2' is either even or odd
  $cmd <mod> <rem> - build every Nth, when '<N> % <mod>' is equal to 'rem'
  $cmd - build every .ino file from ESP8266_ARDUINO_SKETCHES
