 GXINT [options] file(s)
  ld an interactive Geant application and run it. Your compiled
  routines are given in file(s).
  options:

  -F specify (one) extra .for file to link in

  -d driver
        specify the driver for the graphics output. Possible
        values are X11, GKS, or GDDM. Not all are possible on
        systems.
  -v version
        version of the program library to use. Possible values
        include pro ( default ), new and old.
  -g geant_version
        which version of geant to use. Current default is 315.
  -h host
        useful with the -d X11 option only. Specify the hostname
        used for the display. Syntax identical to that of DISPLAY.
        If no hostname is specified, the value of DISPLAY is used.
  -o outputfile
        Do not immediately run GEANT, but produce an executable
        file named outputfile.
  -L path
        additional loader search path. Usefull if additional libraries
        are specified with -l option.  This option may be repeated to
        more than one pathname.
  -l library
        specify additional libraries. This option may be repeated to
        add several libs.
