+" Vim syntax file
+" Language:	gnuplot 3.8i.0
+" Maintainer:	John Hoelzel johnh51@users.sourceforge.net
+" Last Change:	Mon May 26 02:33:33 UTC 2003
+" Filenames:	*.gpi  *.gih   scripts: #!*gnuplot
+" URL:		http://johnh51.get.to/vim/syntax/gnuplot.vim
+"
+
+" thanks to "David Necas (Yeti)" <yeti@physics.muni.cz> for heads up - working on more changes .
+" *.gpi      = GnuPlot Input - what I use because there is no other guideline. jeh 11/2000
+" *.gih      = makes using cut/pasting from gnuplot.gih easier ...
+" #!*gnuplot = for Linux bash shell scripts of gnuplot commands.
+"	       emacs used a suffix of '<gp?>'
+" gnuplot demo files show no preference.
+" I will post mail and newsgroup comments on a standard suffix in 'URL' directory.
+
+" For version 5.x: Clear all syntax items
+" For version 6.x: Quit when a syntax file was already loaded
+if version < 600
+  syntax clear
+elseif exists("b:current_syntax")
+  finish
+endif
+
+" some shortened names to make demo files look clean... jeh. 11/2000
+" demos -> 3.8i ... jeh. 5/2003 - a work in progress...
