# Visualization with DAWNFILE driver
#
#  * Each visualized view is saved to a file "g4_XX.eps"  
#    with the "vectorized" PostScript format.
#
#  * In order to make the file "g4_XX.eps" printable, 
#    append the "showpage" PostScript command to the file 
#    You can do it with the 4th page of the DAWN GUI panel
#    or by editing the file by hand.
#
#  * Set an environmental variable if you wish to 
#    skip DAWN GUI:
#     % setenv G4DAWNFILE_VIEWER "dawn -d"
