#Must already have a version of pgfSweave installed to compile this.
	#This is a workaround for using pgfSweave to compile the vignette
	#in the CRAN version without requiring pgfSweave already.
	#
	#The idea is that before submitting, the developer compiles the source
	#of the vignette with the version of pgfSweave they have been working on 
	#by running this make file.  Then copy the tex file output to inst/doc
	#as an Rnw file (with no code chunks) so that it registers as an official 
	#vignette.  
	#
	#Requires a little finagling to change the path to the example files and 
	#get rid of the \pgfrealjobname line
