        !            11: .SH DESCRIPTION
        !            12: \fIMH\fR processes messages in a particular format.
        !            13: It should be noted that although neither Bell nor Berkeley mailers produce
        !            14: message files in the format that \fIMH\fR prefers,
        !            15: \fIMH\fR can read message files in that antiquated format.
        !            16: 
        !            17: Each user possesses a mail drop box which initially receives
        !            18: all messages processed by \fIpost\fR\0(8).
        !            19: \fIInc\fR\0(1) will read from that drop box and incorporate the new messages
        !            20: found there into the user's own mail folders (typically `+inbox').
        !            21: The mail drop
        !            22: box consists of one or more messages.
        !            23: @BEGIN: MMDFMTS
        !            24: To facilitate the
        !            25: separation of messages, each message begins and ends with
        !            26: a line consisting of nothing but four CTRL\-A (octal 001)
        !            27: characters.
        !            28: @END: MMDFMTS

        !            42: 
        !            43: The general \*(lqmemo\*(rq framework of RFC\-822 is used.
        !            44: A message consists of a block of information in a rigid format,
        !            45: followed by general text with no specified format.
        !            46: The rigidly formatted first part of a message is called the header,
        !            47: and the free-format portion is called the body.
        !            48: The header must always exist, but the body is optional.
        !            49: These parts are separated by an empty line,
        !            50: i.e., two consecutive newline characters.
        !            51: Within \fIMH\fR,
        !            52: the header and body may be separated by a line consisting of dashes:
        !            53:

        !            64: Each header item can be viewed as a single logical line of ASCII
        !            65: characters.
        !            66: If the text of a header item extends across several

        !            68: spaces or tabs.
        !            69: 
        !            70: Each header item is called a component and is composed of a
        !            71: keyword or name, along with associated text.
        !            72: The keyword begins at the
        !            73: left margin, may NOT contain spaces or tabs, may not exceed 63
        !            74: characters (as specified by RFC\-822), and is terminated by a colon (`:').
        !            75: Certain
        !            76: components (as identified by their keywords) must follow rigidly
        !            77: defined formats in their text portions.
