This small package provides a math package that amounts to modifications of the STIX sans serif Roman and Greek letters with most symbols taken from newtxmath which must of course be installed (version 1.43 or higher) and its map file enabled. The best use of this package is for making slides for projection at reasonably good resolution. The four font files in this package are in pfb format, licensed under the SIL OFL, version 1.1. All other LaTeX support files are subject to the LaTeX Project Public License. See 
http://www.ctan.org/license/lppl1.3
for the details of that license. 

Current version: 1.03

Changes in version 1.03
1. Small corrections to accent positions.
2. Changed newtxsf.sty to add definitions of \nabla, \nablaup, \varkappa, \varkappaup, and to change most Greek letters to \mathalpha, where appropriate.
3. The smallest size of parentheses now comes from the text font.

Changes in version 1.02
1. Corrected definitions of \textsquare and \openbox in newtxsf.sty. (Thanks, Jean-François Burnol.)

Changes in version 1.01
Changed AMSa and AMSb to their replacements in newtx 1.43. This should not affect output, but may make more efficient use of math families.
