        !            25: Files output by
        !            26: .I uuencode(1)
        !            27: consist of a header line,
        !            28: followed by a number of body lines,
        !            29: and a trailer line.
        !            30: .I Uudecode(1)
        !            31: will ignore any lines preceding the header or
        !            32: following the trailer.
        !            33: Lines preceding a header must not, of course,
        !            34: look like a header.
        !            35: .PP
        !            36: The header line is distinguished by having the first
        !            37: 6 characters \*(lqbegin\ \*(rq.
        !            38: The word
        !            39: .I begin
        !            40: is followed by a mode (in octal),
        !            41: and a string which names the remote file.
        !            42: A space separates the three items in the header line.
        !            43: .PP
        !            44: The body consists of a number of lines, each at most 62 characters
        !            45: long (including the trailing newline).
        !            46: These consist of a character count,
        !            47: followed by encoded characters,
        !            48: followed by a newline.
        !            49: The character count is a single printing character,
        !            50: and represents an integer, the number of bytes
        !            51: the rest of the line represents.
        !            52: Such integers are always in the range from 0 to 63 and can
        !            53: be determined by subtracting the character space (octal 40)
        !            54: from the character.
        !            55: .PP
        !            56: Groups of 3 bytes are stored in 4 characters, 6 bits per character.
        !            57: All are offset by a space to make the characters printing.
        !            58: The last line may be shorter than the normal 45 bytes.
        !            59: If the size is not a multiple of 3, this fact can be determined
        !            60: by the value of the count on the last line.
        !            61: Extra garbage will be included to make the character count a multiple
        !            62: of 4.
        !            63: The body is terminated by a line with a count of zero.
        !            64: This line consists of one ASCII space.
        !            65: .PP
        !            66: The trailer line consists of \*(lqend\*(rq on a line by itself.
