標準添付のoptparseに似てるけど、オプション項目の置き場所も兼ねてるところが便利そう。

READMEより：

# parse assumes ARGV, otherwise you can pass it your own Array
opts = Slop.parse do
  on :v, :verbose, 'Enable verbose mode'       # boolean value
  on :n, :name, 'Your name', true              # compulsory argument
  on :s, :sex, 'Your sex', :optional => false  # the same thing
  on :a, :age, 'Your age', :optional => true   # optional argument
end

# if ARGV is `-v --name 'lee jarvis' -s male`
opts.verbose? #=> true
opts.name?    #=> true
opts[:name]   #=> 'lee jarvis'
opts.age?     #=> false
opts[:age]    #=> nil
