Usage:
    $0 [OPTION] [<explicit_dependencies>.(sv|svh|v|vh)] <filename>.(sv|v) DESTINATION

Description:
    Script to copy a SystemVerilog file and its dependencies. The script uses
    'Verilator' as its parser back-end to determine the dependent files.

Options:
    -h    Print this help info
    -I    Directory to search for includes

Arguments:
    The script takes two mandatory arguments. The first is the path name
    location of the SystemVerilog/Verilog file to be copied. The second is the
    destination directory into which the files will be copied. Optionally, an
    explicit list of source files may be included before the first mandatory
    argument. These files will always be copied to the DESTINATION.
