new (name=nil, option={}, argv=[], *args)
  • name The name of the command specified on the command line
  • option A Hash or OpenStruct of named command line options. If it’s a Hash it will be converted to an OpenStruct.
  • argv An Array of arguments

option and argv are made available to the routine block. 

routines do
  magic do |options,argv|
    ...
