<hr><a name="_details"></a><h2>Detailed Description</h2>
<a class="el" href="classost_1_1_command_option.html">CommandOption</a> is the base class for all command line options.
<p>
Command line options can be defined statically and used when constructing a command line parser onject using makeCommandOptionParse. This serves only as a base class to <a class="el" href="classost_1_1_command_option_with_arg.html">CommandOptionWithArg</a>, <a class="el" href="classost_1_1_command_option_rest.html">CommandOptionRest</a> or <a class="el" href="classost_1_1_command_option_no_arg.html">CommandOptionNoArg</a> which can also be used to derive more complex classes or even entire applications.<p>
