Gladtex is a utility that enables LaTeX equations within HTML code. You write HTML code as usual, but in addition you can include equations within the special tags .., as if within $$..$$ in LaTeX. Then you run gladtex, which replaces the equations by images. Features include image alignment (baseline of equations agree with baseline of text), GIF and PNG support, transparent backgrounds and antialiasing. The author is Martin G. Gulbrandsen.
