! 7: * This jsMath package makes it possible to display mathematics in HTML pages
! 8: * that are viewable by a wide range of browsers on both the Mac and the IBM PC,
! 9: * including browsers that don't process MathML. See
! 10: *
! 11: * http://www.math.union.edu/locate/jsMath
! 12: *
! 13: * for the latest version, and for documentation on how to use jsMath.
