22 : * \brief Declaration of the keywords validator.
23 : *
24 : * The advgetopt library offers a keywords validator which makes it really
25 : * simple to verify that a command line option matches an exact word without
26 : * having to handle a regular expression. It will also be slightly faster.
27 : *
28 : * The keywords are written as parameters separated by commas (,):
29 : *
30 : * \code
31 : * keywords(on,off)
32 : * \endcode
