   It's more than a way to edit PostScript, and it does not need to be
converted to PDF for inclusion.  Pstoedit allow you to pass PS strings
(labels) through TeX. For example, in Matlab, I just typed

>> t=0:0.01:5;y=exp(-t);plot(t,y);
>> title('Plot of $e\^\{-t\}$');  
>> print -deps exp.ps    

   I ran the result through pstoedit -> gpic -> tex and got the equation
properly typeset in the figure with cmr10.  I had to do a little (trivial)
massaging along the way, but the end result is fine.  One can also run
pstoedit -> mpost, but I am having a little trouble getting the pstoedit
MP output processed by TeX.  In principle, this should possible because MP
can pass arbitrary strings through TeX.  Whether using tpic or MP, a
conversion to PDF is not required.
