# this script is really divided into 2 differenvt section,

# the first section creates, and defines the new PDF file the barcodes 
# using PDF::Reuse::Barcode, then saves the file to disk.

# the second section then opens the pdf file off disk, and places the spline label 
# text in the left-most column of the page. then save the file again.

# the reason for this goofyness, is that i couldnt find a single perl PDF package that handled both barcodes and decent text placement.
