49 
50    Format codes:
51 
52    I - IPv4 address
53    6 - IPv6 address
54    l - 32-bit signed integer
55    L - 32-bit unsigned integer
56    s - 16-bit signed integer
57    S - 16-bit unsigned integer
58    b - 8-bit signed integer
59    B - 8-bit unsigned integer
60    t - ASCII text
61    T - Lease Time, 32-bit unsigned integer implying a number of seconds from
62        some event.  The special all-ones value means 'infinite'.  May either
63        be printed as a decimal, eg, "3600", or as this name, eg, "infinite".
64    f - flag (true or false)
65    A - array of all that precedes (e.g., fIA means array of records of
66        a flag and an IP address)
67    a - array of the preceding character (e.g., fIa means a single flag
68        followed by an array of IP addresses)
69    U - name of an option space (universe)
70    F - implicit flag - the presence of the option indicates that the
71        flag is true.
72    o - the preceding value is optional.
73    E - encapsulation, string or colon-separated hex list (the latter
74        two for parsing).   E is followed by a text string containing
75        the name of the option space to encapsulate, followed by a '.'.
76        If the E is immediately followed by '.', the applicable vendor
77        option space is used if one is defined.
78    e - If an encapsulation directive is not the first thing in the string,
79        the option scanner requires an efficient way to find the encapsulation.
80        This is done by placing a 'e' at the beginning of the option.   The
81        'e' has no other purpose, and is not required if 'E' is the first
82        thing in the option.
83    X - either an ASCII string or binary data.   On output, the string is
84        scanned to see if it's printable ASCII and, if so, output as a
85        quoted string.   If not, it's output as colon-separated hex.   On
86        input, the option can be specified either as a quoted string or as
87        a colon-separated hex list.
88    N - enumeration.   N is followed by a text string containing
89        the name of the set of enumeration values to parse or emit,
90        followed by a '.'.   The width of the data is specified in the
91        named enumeration.   Named enumerations are tracked in parse.c.
92    d - Domain name (i.e., FOO or FOO.BAR).
93    D - Domain list (i.e., example.com eng.example.com)
94    c - When following a 'D' atom, enables compression pointers.
95    Z - Zero-length option
