# parse :foo => "bar"
# #=> Option foo with default value bar
#
# parse [:foo, :baz] => "bar"
# #=> Option foo with default value bar and alias :baz
#
# parse :foo => :required
# #=> Required option foo without default value
#
# parse :foo => 2
# #=> Option foo with default value 2 and type numeric
#
# parse :foo => :numeric
# #=> Option foo without default value and type numeric
#
# parse :foo => true
# #=> Option foo with default value true and type boolean
#
# The valid types are :boolean, :numeric, :hash, :array and :string. If none
# is given a default type is assumed. This default type accepts arguments as
# string (--foo=value) or booleans (just --foo).
#
# By default all options are optional, unless :required is given.
