  # Toolchains used for automated builds:
  # ESP8266 - prebuilt gcc 4.8.2 from ESP8266 Arduino
  # ESP32 - official Espressif toolchain
  #
  # Note: if these are updated, you need to flush the Travis cache
  #
  # (esp-idf is downloaded a zip file. It doesn't fully work this way, but
  # we're just using it for some header files.)
