/* Examples
Shared urbit and urbit-worker binaries:
$ nix-build -A urbit
Static urbit and urbit-worker binaries:
$ nix-build -A urbit --arg enableStatic true
Note that on linux the previous command is equivalent to:
$ nix-build -A urbit --argstr crossSystem x86_64-unknown-linux-musl \
--arg enableStatic true
Static release tarball:
$ nix-build -A tarball --arg enableStatic true
Build a pill:
$ nix-build -A ivory.build
$ nix-build -A brass.build
$ nix-build -A solid.build
