    + +
    + +

    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");
+
