*
* The easiest and fastest way to leverage the project, we use it all the time!
* Commands are designed to mirror the \ref c_sdk and are evaluated in the order they are entered.
* To get started, try running:
* \code
* $ br -help
* \endcode
*
* \section cli_examples Examples
* - \ref cli_show_face_detection
* - \ref cli_age_estimation
* - \ref cli_face_recognition
* - \ref cli_face_recognition_evaluation
* - \ref cli_gender_estimation
* - \ref cli_show_face_detection
