psfig allows the inclusion of postscript in latex documents
   Perhaps the best way to do this is to use the psfig macros written
   by Trevor Darrell. They are available via anonymous ftp from
   whitechapel.media.mit.edu (18.85.0.125) in ./pub/psfig or 
   linc.cis.upenn.edu (130.91.6.8) in the directory ./dist/psfig. You 
   will also need a dvi to PostScript conversion program that supports 
   specials. The ones mentioned in question 1 do, and the first two
   drivers come with a version of psfig ready to use with them. The psfig 
   macros work best with Encapsulated PostScript Files (EPS). In
   particular, psfig will need the file to have a BoundingBox (see 
   Appendix C of the _PostScript Language Reference Manual_). If you 
   don't have an EPS file, life can be difficult. For people who don't
   have ftp access or can't deal with tar files, the files are also
   available from ymir.claremont.edu (134.173.4.23) in
   [anonymous.tex.graphics.psfig].
