% Dumps BWIPP barcode binary to stdout. If `-sn` given, appends a newline after each symbol row, otherwise doesn't.
%
% To run e.g. gs -dNOPAUSE -dBATCH -dNODISPLAY -q -sb=databarexpanded -sd='(01)98898765432106' -so='includetext segments=6' bwipp_dump.ps
% where
% `-sb=` is the BWIPP barcode routine name
% `-sd=` is the data (`sd2=`, `sd3=`, `sd4=` are also available for overspill data > ~2K to get around Ghostscript's arg_str_max)
% `-so=` are options (as space separated key=val pairs (or just key if boolean true))

% For debugging the barcode can be rendered by leaving out `-dBATCH -dNODISPLAY`. Scaling can be specified by `-ss=` (default 2).
