module Mail
  # = Carbon Copy Field
  #
  # The Cc field inherits from StructuredField and handles the Cc: header
  # field in the email.
  #
  # Sending cc to a mail message will instantiate a Mail::Field object that
  # has a CcField as its field type.  This includes all Mail::CommonAddress
  # module instance metods.
  #
  # Only one Cc field can appear in a header, though it can have multiple
  # addresses and groups of addresses.
  #
  # == Examples:
  #
  #  mail = Mail.new
  #  mail.cc = 'Mikel Lindsaar <mikel@test.lindsaar.net>, ada@test.lindsaar.net'
  #  mail.cc    #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar
