     DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
          An implementation of (s)printf() for LPC, with quite a few
          extensions Implemented by Lynscar (Sean A Reith).

          This version supports the following as modifiers:

          " "     pad positive integers with a space.

          "+"     pad positive integers with a plus sign.

          "-"     left adjusted within field size.
                  NB: std (s)printf() defaults to right justification,
                  which is unnatural in the context of a mainly string
                  based language but has been retained for
                  "compatability".

          "|"     centered within field size.

          "="     column mode if strings are greater than field size.
                  This is only meaningful with strings, all other
                  types ignore this. Columns are auto-magically word
                  wrapped.

          "#"     table mode, print a list of '\n' separated 'words'
                  in a table within the field size.  only meaningful
                  with strings.

          n       specifies the field size, a '*' specifies to use the
                  corresponding arg as the field size.  If n is
                  prepended with a zero, then is padded zeros, else it
                  is padded with spaces (or specified pad string).

          "."n    precision of n, simple strings truncate after this
                  (if precision is greater than field size, then field
                  size = precision), tables use precision to specify
                  the number of columns (if precision not specified
                  then tables calculate a best fit), all other types
                  ignore this.

          ":"n    n specifies the fs _and_ the precision, if n is
                  prepended by a zero then it is padded with zeros
                  instead of spaces.

          "@"     the argument is an array.  the corresponding
                  format_info (minus the "@") is applyed to each
                  element of the array.

          "'X'"   The char(s) between the single-quotes are used to
                  pad to field size (defaults to space) (if both a
                  zero (in front of field size) and a pad string are
                  specified, the one specified second overrules).
                  NOTE:  to include "'" in the pad string, you must
                  use "\'" (as the backslash has to be escaped past
                  the interpreter), similarly, to include "

          The following are the possible type specifiers.

          %       in which case no arguments are interpreted, and a
                  "%" is inserted, and all modifiers are ignored.

          O       the argument is an LPC datatype.

          s       the argument is a string.

          d, i    the integer arg is printed in decimal.

          c       the integer arg is to be printed as a character.

          o       the integer arg is printed in octal.

          x       the integer arg is printed in hex.

          X       the integer arg is printed in hex (with A-F in
                  capitals).

          f       floating point number
