- * Convert a set of bit flags to printable format.

- * Arguments:

- * buffer      - Buffer to output string to.
- * size                - Size of buffer in bytes.  Buffer is always NUL terminated.
- * flags       - Binary flags to output
- * bitfield    - Textual representation of bits to output.  This string
- *               is in the following format:
- *
- *     Option byte 0x01 STRING1 0x02 STRING2 ....
- *
- * The first byte is an option byte to snprintb().  Currently the only option
- * supported is 0x08, which indicates that the flags should be output in
- * octal format; if the option byte is any other value, the flags will be
- * output in hexadecimal.
- *
- * After the option bytes are series of text strings, prefixed by the number
- * of the bit they correspond to.  For example, the bitfield string:
- *
- *     "\020\01FLAG1\02FLAG2\03FLAG3\04FLAG4"
- *
- * will output the following string if "flags" is set to 0x09:
- *
- *     0x2<FLAG1,FLAG4>
- *
- * You don't have to use octal in the bitfield string, that's just the
- * convention currently used by the nmh code.  The order of flags in the
- * bitfield string is not significant, but again, general convention is
- * from least significant bit to most significant.
