+usage_description="
+Installs a GitLab project repo's release binary to \$HOME/bin or /usr/local/bin, unpacking it from a tarball or zip if necessary
+
+If the release file is a tarball or zip file then it'll auto-unpack it, but you must specify the path to the binary in the unpack
+
+If version is not specified, determine the latest release and installs that
+
+If the release URL title/path is more complicated than the convention of following the version number, such as is the case for Kustomize, then you'd need to call install_binary.sh with the URL path instead of using this script, see setup/install_kustomize.sh
