Usage: ocarina-config [OPTIONS]
Options:
        No option:
            Output all the flags (compiler and linker) required
            to compile your program.
        [--prefix[=DIR]]
            Output the directory in which Ocarina architecture-independent 
           files are installed, or set this directory to DIR.
        [--exec-prefix[=DIR]]
            Output the directory in which Ocarina architecture-dependent 
           files are installed, or set this directory to DIR.
        [--version|-v]
            Output the version of Ocarina.
        [--config]
            Output Ocarina's configuration parameters.
        [--runtime[=<Runtime_Name>]]
            Checks the validity and the presence of the given runtime and 
            then, outputs its path. Only one runtime can be requested at 
            a time. If no runtime name is given, outputs the root directory
            of all runtimes.
        [--libs]
            Output the linker flags to use for Ocarina.
        [--projects]
            Output the path to GNAT Project files for Ocarina
        [--properties]
            Output the location of the standard property file.
        [--resources]
            Output the location of resource files 
            (typically the standard properties)
        [--cflags]
            Output the compiler flags to use for Ocarina.
        [--help]
            Output this message
