In general, this executable is built by building the `foo_export_$DEVICE` target.
Building an executable destined to run on a host machine (i.e., under `sw/host`) will output a host excecutable under `build-bin/sw/host`, which can be run directly.

+## Troubleshooting
+If you encounter an error running `./meson_init.sh` you could re-run using the `-f` flag which will erase any existing building directories to yield a clean build. This sledgehammer is only intended to be used as a last resort when the existing configuration is seriously broken.
+```console
+$ ./meson_init.sh -f
+```
+If any `meson.build` files are changed the configuration can be regenerated by passing the `-r` flag to `./meson_init.sh`
+```console
+$ ./meson_init.sh -r
+```
