Xfig: LaTeX style equations and symbols

This solution is easier than what I posted before
1. xfig
2. Text Flag-Speical Flag-Speical. For sure the equations are inside $ ... $
3. Export: Combined PS/LaTeX (both parts), remember to type the name with extension .pstex
4. Copy two files (sutest.pstex_t, sutest.pstex) to the directory (don't need to modify)
5.
\documentclass{article}
\usepackage{epsfig}
\usepackage{color}
\setlength{\textwidth}{100cm} \setlength{\textheight}{100cm}
\begin{document}
\pagestyle{empty}
\input{sutest.pstex_t}
\end{document}
6. after compile and get dvi file:
dvips -E sutest.dvi -o test.eps

The output eps file doesn't need to be cropped.
