class CmdSay(Command):
    """Say something to the characters in the same area.

    Usage:

      |gsay [[<adverb>] [to <character>],] <message>|n

    This command has a couple optional strings. as you see, the text
    within brackets, [...] are optional, while text in <...> are to be
    replaced, and this technical jargon probably means little, so
    perhaps examples would be better:

      |gsay Good evening.|n
      |wYou say, "Good evening."|n

    Or:

      |gsay loudly, Good evening!|n
      |wYou loudly exclaim, "Good evening!"|n

    In the second example, you gave an |wadverb|n that ends in
    |w-ly|n. Also, the exclamation point changes the 'say' to an
    'exclaim'. A question mark changes 'say' to 'ask'.

    If you start your message with an adverb, but want that adverb
    |win|n the message and not |waffecting|n the message, surround it
    with quotes. For instance:

      |gsay actually, it is pronounced gah-nome.
      |wYou say actually, "it is pronounced gah-nome."
      |gsay "actually, it is pronounced gah-nome."
      |wYou say, "actually, it is pronounced gah-nome."|n

    Of course, adverbs that affect the message are lowercase, and
    messages usually begin with an uppercase, as in:

      |gsay Actually, it is pronounced Gah-nome.
      |wYou say, "Actually, it is pronounced Gah-nome."|n

    Because this command is so common, you can also use ", as in:

      |g"What's going on?|n

    You can also direct your message to a particular person (or
    thing), as in:

      |gsay to heron, How do you do?
      |wYou ask the purple heron, "How do you do?"|n
      "What can I do for you?" asks the purple heron.

    Since you might be having a conversation with a character, you can
    use the |gsayto|n to target the same person. For instance:

      |gsay to pet Who's a widdle cutie?
      |wYou ask wee beastie, "Who's a widdle cutie?"
      |gsayto You are!
      |wYou exclaim to wee beastie, "You are!"|n

    You can replace the 'say' command with any of the following:

      - shout
      - scream
      - respond
      - reply
      - yell
      - ask
