Extend the "exporsitive" tool that converts Web+ bookmarks to an HTML file, with the option to convert to Chrome format as well. Change the name to someting more obvious, like "bookmarkconverter".

The tool now has to accept the output format as further parameter and give out the help on usage when called without parameters (or when called with -h or --help). E.g.:

Converts WebPositive bookmarks to various formats.

Usage: bookmarkconverter [option] [path]

    -f  --format FORMAT     choses the format (HTML, CHROME)
    -h  --help              prints this help text
	
    path                    optionally sets the path to the Web+ bookmarks
                            (default: ~/config/settings/WebPositive/Bookmarks)
