irbtk.rb

frozen_string_literal: false

irbtk.rb - irb with Ruby/Tk

If you want to use 'multi-tk.rb', give option '--multi-tk'.
And if you want to use 'remote-tk.rb', give option '--remote-tk'.
If you want both, you don't need to give both options, because
'remote-tk.rb' includes 'multi-tk.rb'.
( There is no trouble even if you give both options. )
