% Utility program for converting Japanese fonts produced by Macromedia's
% Rollup program to Type 0 fonts suitable for use with Ghostscript.
%
% Rollup produces the following files, where xxx is the font name:
%	xxx-H, xxx-SA, xxx-SB, xxx-SK, xxx-SR, xxx-UG
%	JIS83-1_COD
%	JIS83-1_CSA
% The _COD and _CSA files are large files containing the actual
% character outline data; they may theoretically be shared between
% multiple fonts.
%
% rollconv.ps converts the above to files named:
%	fff.ps
%	fff.COD
%	fff.CSA
%	fff.CSR
% where fff is a font file name provided by the user at conversion time.
% The fff.ps file is the actual font file to be loaded with `run'
% or placed in a Fontmap or a directory named by [GS_]FONTPATH;
% the other two files must be present at runtime in a directory that is
% on Ghostscript's search path (-I, GS_LIB, GS_LIB_DEFAULT).
%
% The normal way to invoke this program is
%	gsnd -- rollconv.ps xxx fff InDir CDir OutDir
% (assuming that gsnd is an alias for gs -dNODISPLAY), where:
%	xxx is the font name;
%	fff is the base part of the output file name;
%	InDir is the name of the directory containing the xxx-* input files;
%	CDir is the name of the directory containing the _COD and _CSA
%	  input files (typically the same as InDir);
%	OutDir is the name of the directory where the output should be written
%	  (OutDir must already exist).
% For example:
%	gsnd -- rollconv.ps HGGothicBPRO gothic /gs/k/rufonts/Gothic \
%	  /gs/k/rufonts/Gothic /gs/k/gsfonts
% To suppress output messages, you may insert -q:
%	gsnd -q -- rollconv.ps ...
%
% This program assumes that the files have been FTP'ed from a Macintosh and
% therefore have 128 bytes of garbage at the beginning.  If you have
% transferred them in some manner that avoids this, change true to false
% in the following line.
/fromMac true def
% The FontName of the converted font is xxx-83pv-RKSJ-H.  In order to
% use a converted font with Ghostscript, you may either load it explicitly
% at run time, e.g.,
%	(gothic.ps) run
% or you may add an entry to the Fontmap file, in the form:
%	/HGGothicBPRO-83pv-RKSJ-H  (gothic.ps)  ;
% which will allow the font to be loaded automatically.  After
% loading the font, by either method, you can select it in the usual way:
%	/HGGothicBPRO-83pv-RKSJ-H findfont 36 scalefont setfont
% or
%	/HGGothicBPRO-83pv-RKSJ-H 36 selectfont
