Subject: How to call an foreign program(compiled) from ruby?

Hi, I am trying to use some bin(like exe files under windows) file
under linux , these program is compiled from c++ source, can be
executed in command line . I am just wondering what is the simple way
to call these program from with the ruby program?

i  think Rake might be the answer , I am not look things like FFI that
can handle c source , I just need to call an program ,pass it some
command line parameter, get some return data or some result file ,
that's enough

i notice some gem (generally speaking) can have some inbound bin file
in it's sub folder, I don't know how they glued together with ruby

can someone give some hint?

Thank you very much
