## Nautilus
## SCRIPT: 00_1pdfFile_SHOW_via_gs.sh
##
## PURPOSE: Runs the 'gs' (Ghostscript) command in an 'xterm'
##          to show a user-selected PDF file.
##
## METHOD:  The 'xterm' allows the user to page through the PDF
##          using 'gs' commands (or simply hitting Return) in the X-terminal.
##
## HOW TO USE: In Nautilus, navigate to a PDF file, select it,
##             right-click and choose this Nautilus script to run.
##
## WARNING: The output of 'gs' in the X-terminal gets pretty messy.
