XITS is a Times-like typeface for mathematical and scientific publishing, based
on STIX fonts. The main mission of XITS is to provide a version of STIX
fonts enhanced with the OpenType MATH table, making it suitable for high
quality mathematic typesetting with OpenType math-capable layout systems, like
Microsoft Office 2007+, XeTeX and LuaTeX.
XITS fonts are distributed under the Open Font License, version 1.1.
The preferred way for modifying the fonts is by editing the SFD files under
sources directory in the source repository, using FontForge. When
submitting patches, please make sure they are as clean as possible, avoiding
any unrelated or unnecessary changes.
To build the fonts from source you need GNU Make, FontForge Python module, and FontTools.
