  You should now have a running version os PSint, or whatever
you called it...

  This interpretor has a few options that you can use at
run time (doesn't work on Vaxs) :

  Syntax :
    PSint [-Help]
          [-Start [startup_filename]]
          [-Run command(s)]
          [file1 file2...]

  * Help  : reminder of PSint options
  * Start : you can specify a startup-file :
      At program launch time, a PostScript source file is
     loaded. If Start option is specified, then that will
     be that file. Otherwise, we first try to find a `.ps'
     file in the user home directory (`~/.ps'). If there is
     none, then we look in the current working directory to
     find a file called `profile.ps' and execute it.
       If the Start option is given with no file name after,
     then no startup file will be loaded.
  * Run : you can specify some commands to be executed as
     soon as PSint is loaded. Multiple commands are allowed,
     if given within quotes :

         $ PSint -Run `1 2 add = quit'
      will print `3', then quit.

 * Files : PostScript source files can be executed as soon as
     you get under PSint.

   A common syntax would be :

   $ PSint -Run A4 myPSfile -Run quit

  This will :
     * Run PSint
     * Eventually load a startup file (`~/.ps' or `./profile.ps')
     * Execute the `A4' command (creates a output page)
     * Execute your file
     * Quit.

  Some useful things have been added in the `profile.ps' file
given in this distribution :

  * statusdict is created here
  * Initial FontDirectory contents is done here
  * findfont is redefined to substitute any unknown font with
    /Times-Roman
  * Hershey font loading stuff is declared here
  * Some built-in page formats are declared : 
       page      : a small 500 pixels high window, A4-like
       bigpage   : a big 765 pixels high window, A4-like
       landscape : a full-screen 1024 pixels wide window,  A4-like
  * Some classic page formats are defined :
       letter
       note
       legal
       a4
