	Functionality:
		Generation of JLCPCB PCBA 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/bom2grouped_csv_jlcpcb.xsl" "%I"
-->
<!--
    @package
    Generates a JLCPCB PCBA service compatible BOM

	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
    Comment,Designator,Footprint,LCSC

    The command line is
        xsltproc -o "%O.csv" "full_path/bom2grouped_csv_jlcpcb.xsl" "%I"
