  NAME

    uuencode - Format of a file encoded with uuencode

  DESCRIPTION

    An encoded file produced by the uuencode command consists of a header
    line, a number of body lines, and a trailer line.  The uudecode command
    will ignore any lines preceding the header or following the trailer.  Any
    lines preceding a header line must not have the same format as the header
    line.

    The header line contains the string begin, a mode (in octal), and a string
    which names the remote file.  Each of these items is separated by a space.

    The body consists of a number of lines, each no more than 62 characters
    long (including the trailing newline).  Each line consists of a character
    count followed by encoded characters and ending in a newline.  The
    character count is a single printing character, and represents an integer
    indicating the number of bytes the rest of the line represents.  Such
    integers are always in the range from 0 to 63, and can be determined by
    subtracting the value of the character space (octal 40) from the
    character.

    Groups of 3 bytes are stored in 4 characters, 6 bits per character.  All
    are offset by a space to make the characters printable.  The last line may
    be shorter than the normal 45 bytes.  If the size is not a multiple of 3,
    this fact can be determined by the value of the count on the last line.
    Extra garbage is included to make the character count a multiple of 4.
    The body is terminated by a line with a count of zero, consisting of one
    ASCII space.

    The trailer line contains only the string end.
