+% 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
