  - Use different compilers (gcc, clang)
  - Use different gcc versions
  - Cross-compile for Windows 32bit and 64bit using MinGW and WINE
  - Cross-compile for RTEMS 4.9 and 4.10 (Base >= 3.16.2)
  - Compile on MacOS
  - Built dependencies are cached (for faster builds)

+#### Build Worker Images
+The AppVeyor documentation on build worker images doesn't seem to fully
+describe the way things are handled internally.
+
+The tested and suggested reproducible way of defining the build worker image
+is shown in the example configuration files:
+
+ - Set the default image using the `image:` tag.
+ - Override the image for specific jobs by setting the
+   `APPVEYOR_BUILD_WORKER_IMAGE` environment variable.
