% Construct an inverse map from CIDs to codes.
% Create an inverse map from CIDs to code values.
% We only use this for 16-bit Unicode, so it has some limitations.
% After invoking .cmap2code, loading a CMap file prints out the map
% instead of doing what it usually does. For example:
%
% gs -dNODISPLAY -dBATCH lib/cid2code.ps -c .cmap2code\
% -f Resource/CMap/UniJIS-UCS2-H > mapfile
