/**
* @brief Attention handler application main()
*
* This is the main interface to the hardware diagnostics application. This
* application will either be loaded as a daemon for monitoring the attention
* gpio or it will be loaded as an application to analyze hardware and
* diagnose hadrware error conditions.
*
* Usage:
* --analyze: Analyze the hardware
* --start: Start the attention handler
* --stop: Stop the attention handler
* --all <on|off>: All attention handling
* --vital <on|off>: Vital attention handling
* --checkstop <on|off>: Checkstop attention handling
* --terminate <on|off>: Terminate Immiediately attention handling
* --breakpoints <on|off>: Breakpoint attention handling
*
* Example: openpower-hw-diags --start --vital off
*
* @return 0 = success
