/* Original Author:         Andrew Trevorrow
   Implementation: Modula-2 under VAX/UNIX 4.2 BSD
   Date Started:   June, 1986 (based on DCLInterface under VAX/VMS)

   Description:
   InitSysInterface gets the DVItoVDU command line and initializes
   the DVI file name and command option values.

   This version converted to C and ported to BSD and System V UNIX by
   some chaps at Kernel Technology up to September 1989.  Contact
   mjh@uk.co.kernel (Mark J. Hewitt) with bug fixes etc.

   Involved were:	Mark J. Hewitt
   			Dave Dixon
			Marc Hadley
