Creating the combined figure

(1) Set the 'special' flag in xfig.

(2) Generate two files using:

$ make overview.pstex overview.pstex_t -n -W overview.fig
fig2dev -L pstex  overview.fig overview.pstex
fig2dev -L pstex_t -p overview.pstex  overview.fig overview.pstex_t

(3) include the graphics in your latex by doing

\input{overview.pstex_t}

(4) You may need some graphcs mode thing, such as

\usepackage{epsfig}


(5) I use this macro

\newcommand{\figput}[2]{%
\begin{figure}%
 \begin{center}%
  \input{#1.pstex_t}%
 \end{center}%
 \caption{\mbox{\tt (#1.eps)} #2}%
 \label{fig:#1}%
\end{figure}%
}

which I use like this

\figput{overview}{How the components fit together.  The program is
written in an extension to C that has some implicit and explicit
atomicity.  The compiler produces an executable that, using a
combination of the run-time library and the hardware, runs the
program.  The interface between the executable and the
hardware-and-library is called the transactional API\@.}

\usepackage[dvips]{graphicx,color}

Scaling the combined figure

#!/usr/bin/perl
# convert xfig pstex to eps
# usage pstex 
$basename=shift;
open TEX, ">$basename.tex" or die "Cannot open $basename.tex for write :$!";
