* A formatter of help messages for command line options.
*
*
* Example:
*
*
*
* Options options = new Options();
* options.addOption(OptionBuilder.withLongOpt("file").withDescription("The file to be processed").hasArg().withArgName("FILE").isRequired().create('f'));
* options.addOption(OptionBuilder.withLongOpt("version").withDescription("Print the version of the application").create('v'));
* options.addOption(OptionBuilder.withLongOpt("help").create('h'));
*
* String header = "Do something useful with an input file\n\n";
* String footer = "\nPlease report issues at http://example.com/issues";
*
* HelpFormatter formatter = new HelpFormatter();
* formatter.printHelp("myapp", header, options, footer, true);
*
*
* This produces the following output:
*
*
* usage: myapp -f <FILE> [-h] [-v]
* Do something useful with an input file
*
* -f,--file <FILE> The file to be processed
* -h,--help
* -v,--version Print the version of the application
*
* Please report issues at http://example.com/issues
