FONTLOG for XITS
-------------------
This file provides detailed information on the XITS font software. This
information should be distributed along with the XITS fonts and any derivative
works.
Basic Font Information
--------------------------
XITS is a Times-like typeface for mathematical and scientific publishing, based
on STIX fonts project. The main mission of XITS is to provide a version of STIX
fonts enriched with the OpenType MATH extension, making it suitable for high
quality mathematic typesetting with OpenType MATH capable layout systems, like
MS Office 2007 and the new TeX engines XeTeX and LuaTeX.
XITS development is currently hosted on:
http://github.com/khaledhosny/xits-math
Feature requests, bug reports and patches should be directed to our issue
tracker.
