+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.
