+dvipdfmx and xdvipdfmx for TeX Live
+===================================
+
+This package is released under the GNU GPL, version 2, or (at your
+option) any later version.
+
+dvipdfmx is now maintained as part of TeX Live.
+
+Mailing list for bug reports and all discussion:
+https://lists.tug.org/dvipdfmx; anyone can join the list, but it is not
+necessary to join to post. Archives are public.
+
+xdvipdfmx
+=========
+xdvipdfmx is an extended version of dvipdfmx, and is now incorporated in
+the same sources.
+
+The extensions provided by xdvipdfmx provide support for the Extended DVI
+(.xdv) format used by xetex, including support for platform-native fonts
+and the xetex graphics primitives, as well as Unicode/OpenType text.
+
+Like its direct ancestor dvipdfmx, this is free software and may be
+redistributed under the terms of the GNU General Public License,
+version 2 or (at your option) any later version.
+
+Jonathan Kew mentions that in the past, XeTeX used a Mac-specific
+program xdv2pdf as the backend instead of xdvipdfmx. xdv2pdf supported
+a couple of special effects that are not yet available through
+xdvipdfmx: the Quartz graphics-based shadow support, AAT "variation"
+fonts like Skia, transparency as an attribute of font color, maybe other
+things. It would be nice for those things to continue to be supported,
+if anyone is looking for some nontrivial but not-impossible job and
+happens across this file.
+
+
+1. Introduction
+ ------------
+
+ The dvipdfmx (formerly dvipdfm-cjk) project provides an eXtended version
+ of the dvipdfm, a DVI to PDF translator developed by Mark A. Wicks.
+
+ The primary goal of this project is to support multi-byte character
+ encodings and large character sets for East Asian languages. The secondary
+ goal is to support as many features as pdfTeX developed by Han The Thanh.
+
+ This project is a combined work of the dvipdfm-jpn project by Shunsaku
+ Hirata and its modified one, dvipdfm-kor, by Jin-Hwan Cho.
+
+
+2. Installation
+ ------------
+
+ Currently, dvipdfmx is distributed as part of TeX Live. For TeX Live users,
+ please refer to the following site
+
+ https://www.tug.org/texlive/svn/
+
+ for an instruction on how to obtain and build the dvipdfmx program.
+
+3. Random number generating function
+ ---------------------------------
+
+ Prefixes of font names are calculated by using a function which
+ generates pseudo random numbers. In order to obtain a unique
+ prefix on all platforms when current time is common, a special
+ function MT19937, coded by Takuji Nishimura and Makoto Matsumoto,
+ is used. The header of the C program by Takuji Nishimura and
+ Makoto Matsumoto is the following:
+
+ A C-program for MT19937, with initialization improved 2002/1/26.
+ Coded by Takuji Nishimura and Makoto Matsumoto.
+
+ Before using, initialize the state by using init_genrand(seed)
+ or init_by_array(init_key, key_length).
