     wxCmdLineEntryDesc::flags field is a combination of these bit masks.

     parameter - this may be changed by giving non-default flags to it, i.e. use
-    wxCMD_LINE_OPTION_MANDATORY to require that the option is given and
-    wxCMD_LINE_PARAM_OPTIONAL to make a parameter optional. Also,
-    wxCMD_LINE_PARAM_MULTIPLE may be specified if the programs accepts a

+    Also, @c wxCMD_LINE_PARAM_MULTIPLE may be specified if the programs accepts a
     variable number of parameters - but it only can be given for the last
     parameter in the command line description. If you use this flag, you will
     probably need to use wxCmdLineEntryDesc::GetParamCount() to retrieve the
     number of parameters effectively specified after calling
     wxCmdLineEntryDesc::Parse().

     a colon, an equal sign or white space) between the option name and its
     value. By default, no separator is required.
+
+    @c wxCMD_LINE_SWITCH_NEGATABLE can be specified if you want to allow the
+    user to specify the switch in both normal form and in negated one (e.g.
+    /R-). You will need to use wxCmdLineParser::FoundSwitch() to distinguish
