usage="$(command cat <<\END
Usage: build [-m ARCH] [-c CPU] [-d CMD] [-i IMAGE] [-s] [-w]
Options:
-m ARCH `uname -m` from the target machine; defaults to `uname -m`
from the local machine
-c CPU generate machine instructions for CPU of this type; this
value gets passed as `-march` to gcc; inferred from ARCH
if not set explicitly
-d CMD build in a Docker container and use CMD as the `docker`
command; e.g., `-d docker` or `-d podman`
-i IMAGE build in this Docker image; inferred from ARCH if not set
explicitly
-s install whatever software is necessary for build to
succeed; on some operating systems this option is not
supported; on others it can have partial effect
-w automatically download tarballs for dependencies if they
don't already exist in ./deps; dependencies are described
in ./build.info
