comment: 
- !ruby/struct:SM::Flow::P 
 body: Runs the specified command string as a subprocess; the subprocess's standard input and output will be connected to the returned <tt>IO</tt> object. If cmd_string starts with a ``<tt>-</tt>'', then a new instance of Ruby is started as the subprocess. The default mode for the new file object is ``r'', but mode may be set to any of the modes listed in the description for class IO.
- !ruby/struct:SM::Flow::P 
 body: If a block is given, Ruby will run the command as a child connected to Ruby with a pipe. Ruby's end of the pipe will be passed as a parameter to the block. At the end of block, Ruby close the pipe and sets <tt>$?</tt>. In this case <tt>IO::popen</tt> returns the value of the block.
- !ruby/struct:SM::Flow::P 
 body: "If a block is given with a cmd_string of ``<tt>-</tt>'', the block will be run in two separate processes: once in the parent, and once in a child. The parent process will be passed the pipe object as a parameter to the block, the child version of the block will be passed <tt>nil</tt>, and the child's standard in and standard out will be connected to the parent through the pipe. Not available on all platforms."
