Class HelpFormatter
HelpFormatter formats help for console shells. Can format to either text or XML formats. Uses ConsoleOptionParser methods to generate help.
Generally not directly used. Using $parser->help($command, 'xml'); is usually how you would access help. Or via the --help=xml
option on the command line.
Xml output is useful for integration with other tools like IDE's or other build tools.
