The cl::extrahelp class is a nontemplated class that allows extra +help text to be printed out for the --help option.
+ ++namespace cl { + struct extrahelp; +} ++ +
To use the extrahelp, simply construct one with a const char* +parameter to the constructor. The text passed to the constructor will be printed +at the bottom of the help message, verbatim. Note that multiple +cl::extrahelp can be used but this practice is discouraged. If +your tool needs to print additional help information, put all that help into a +single cl::extrahelp instance.
+For example:
++ cl::extrahelp("\nADDITIONAL HELP:\n\n This is the extra help\n"); ++
