使用Ruby gem部署shell脚本并安装在bin目录中

I wish to place a shell script in my gem's bin dir, along with other Ruby programs that belong to the package. I wish to have this shell script installed in the bin directory as-is (that is, no wrappers). Is that possible with Ruby gems at all? I would be happy with post-install hooks if not otherwise possible. Anybody has any experience with this?I wish to place a shell script in my gem's bin
