A statically compiled binary will be placed in the `result` directory. A statically compiled binary will be placed in the `result` directory.
A full release, which cross-compiles binaries for all supported platforms, can
be generated by doing:

nix build '.#release'
```
*NOTE* that cross-compiling will download a separate build environment for each
target platform, which can take up quite a bit of disk space (>10GB).
