	Functionality:
		Generation of Digi-Key ordering system compatible BOM

    How to use this is explained in eeschema.pdf chapter 14.  You enter a command line into the
    netlist exporter using a new (custom) tab in the netlist export dialog.
    The command line is
        xsltproc -o "%O.csv" "FullPathToFile/bom2groupedCsv.xsl" "%I"
-->
<!--
    @package
	Functionality:
    * Generate a comma separated value BOM list (csv file type).
    * Components are sorted by ref and grouped by same value+footprint
    One value per line
    Fields are
    Reference, Quantity, Value, Footprint, Datasheet

    The command line is
        xsltproc -o "%O.csv" "FullPathToFile/bom2groupedCsv.xsl" "%I"
