%* Description: LaTeX style file allowing for Encapsulated PostScript
%*              files to be included in LaTeX, contains macro 
%*              definitions building on the basic epsf capabilities 
%*              (see epsf.sty).
%*
%* Needs to be included as follows: 
%*   \documentstyle[<...>,postscript,<...>]{<...>}
%* 
%* Commands:
%*   \postscript{<eps_file_name>}{<factor>}
%*     Will include the Encapsulated PostScript document in the file 
%*     <eps_file_name> into the current LaTeX document.
%*
%*     Typical usage:
%*       \begin{figure}
%*       \postscript{my_picture.eps}{1}
%*       \caption{my picture}
%*       \end{figure}
%*
%*   \fpostscript{<eps_file_name>}{<factor>}
%*     Similar to \postscript, but will draw a frame around the eps 
%*     picture. The frame is drawn by TeX, so it will show up in a 
%*     dvi preview. Hence, one can "debug" LaTeX files with 
%*     Encapsulated PostScript, without actually generating
%*     PostScript. Just xdvi (or xpreview) the .dvi file and the eps 
%*     will show up as an empty frame.
%*
%*     <factor> determines the final size of the included picture. 
%*     It is a factor (e.g., 0.5) relating to the actual textwidth 
%*     of the document. Hence, if the a4wide style is used, 
%*     \postscript{my_picture.eps}{1} will scale the picture to the 
%*     full a4wide textwidth, whereas the twocolumn style option will 
%*     result in scaling to the width of a single column.
%*     Note: using \begin{figure*} allows one to have the picture 
%*     scaled to the full textwidth, even in twocolumn style.
%*     Factor 0 means: keep the natural size of the image.
%*
%*     For more direct control of PostScript inclusion, use espf.sty 
%*     directives directly (see /usr/local/tex/inputs/epsf.sty).
%*
%*     If verbose output is wanted about the inclusion proces:
%*     \epsfverbosetrue
%*
%*     To facilitate the draft/final version generation process,
%*     \epsincl is provided. \epsincl is nothing but \postscript
%*     or \fpostscript, depending on whether \drafttrue has
%*     been set.
%*
