TITLE: Create detached signatures for the butane @@VERSION@@ release

Please create detached signatures for the binaries we will upload to GitHub for the `butane` @@VERSION@@ release.  This is a manual process for now, pending the automation discussed in https://pagure.io/robosignatory/issue/53 and https://github.com/coreos/fedora-coreos-tracker/issues/335.

The binaries themselves have been built in koji.  Here is a small script to grab all of the rpms and the files out of the rpms and name them appropriately:

```
EOF
    make_script
    cat <<'EOF'
```

After running this you should end up with a directory with files in it like:

```
$ ls -1
butane-aarch64-apple-darwin
butane-aarch64-apple-darwin.asc
butane-aarch64-unknown-linux-gnu
butane-aarch64-unknown-linux-gnu.asc
butane-ppc64le-unknown-linux-gnu
butane-ppc64le-unknown-linux-gnu.asc
butane-s390x-unknown-linux-gnu
butane-s390x-unknown-linux-gnu.asc
butane-x86_64-apple-darwin
butane-x86_64-apple-darwin.asc
butane-x86_64-pc-windows-gnu.exe
butane-x86_64-pc-windows-gnu.exe.asc
butane-x86_64-unknown-linux-gnu
butane-x86_64-unknown-linux-gnu.asc
```
