Question about creating RubyGems package:

I want to include a shell script into bin/ directory.
I tried to create and install my package. It was done successfully.
But gem command cannot detect the shell script is not a ruby script.
It means that '/usr/local/bin/myscript', for example, load a script
'/usr/local/lib/ruby/gems/1.8/gems/myapp-0.0.1/bin/myscript' as
Ruby script, and got error becasuse the latter is not ruby script
but a shell script.

Give me some advice.
