comment: 
- !ruby/struct:SM::Flow::P 
  body: The GetoptLong class allows you to parse command line options similarly to the GNU getopt_long() C library call. Note, however, that GetoptLong is a pure Ruby implementation.
- !ruby/struct:SM::Flow::P 
  body: GetoptLong allows for POSIX-style options like <tt>--file</tt> as well as single letter options like <tt>-f</tt>
- !ruby/struct:SM::Flow::P 
  body: The empty option <tt>--</tt> (two minus symbols) is used to end option processing. This can be particularly important if options have optional arguments.

  body: "Here is a simple example of usage:"
