-Command Line Parser
-===================

-CommandLineParser
---------
-.. ocv:class:: CommandLineParser
-
-The CommandLineParser class is designed for command line arguments parsing
-
-
-    .. ocv:function:: CommandLineParser::CommandLineParser(int argc, const char * const argv[], const std::string keys)
-
-        :param argc: 
-        :param argv: 
-        :param keys: 
-
-    .. ocv:function:: T CommandLineParser::get<T>(const std::string& name, bool space_delete = true)
-
-        :param name: 
-        :param space_delete: 
-
-    .. ocv:function:: T CommandLineParser::get<T>(int index, bool space_delete = true)
-
-        :param index: 
-        :param space_delete:  
-
-    .. ocv:function:: bool CommandLineParser::has(const std::string& name)
-
-        :param name: 
-
-    .. ocv:function:: bool CommandLineParser::check()
-
-
-    .. ocv:function:: void CommandLineParser::about(std::string message)
-    
-        :param message: 
-
-    .. ocv:function:: void CommandLineParser::printMessage()
-
-    .. ocv:function:: void CommandLineParser::printErrors()
-
-    .. ocv:function:: std::string CommandLineParser::getPathToApplication()
-
-
-The sample below demonstrates how to use CommandLineParser:
-
-::
-
-    CommandLineParser parser(argc, argv, keys);
-    parser.about("Application name v1.0.0");
-
-    if (parser.has("help"))
-    {
-        parser.printMessage();
-        return 0;
-    }
-
-    int N = parser.get<int>("N");
-    double fps = parser.get<double>("fps");
-    std::string path = parser.get<std::string>("path");
-
-    use_time_stamp = parser.has("timestamp");
-
-    std::string img1 = parser.get<string>(0);
-    std::string img2 = parser.get<string>(1);
-
-    int repeat = parser.get<int>(2);
-
-    if (!parser.check())
-    {
-        parser.printErrors();
-        return 0;
-    }
-
-Syntax:
-
-::
-
-    const std::string keys = 
-        "{help h usage ? |      | print this message   }"
-        "{@image1        |      | image1 for compare   }"
-        "{@image2        |      | image2 for compare   }"
-        "{@repeat        |1     | number               }"
-        "{path           |.     | path to file         }"
-        "{fps            | -1.0 | fps for output video }"
-        "{N count        |100   | count of objects     }"
-        "{ts timestamp   |      | use time stamp       }"
-        ;
-
-Use:
-
-::
-
-    # ./app -N=200 1.png 2.jpg 19 -ts
-
-    # ./app -fps=aaa
-    ERRORS:
-    Exception: can not convert: [aaa] to [double]
