Detailed Description

       Commandline and configuration file parsing helper.

       Args is a commandline parsing helper. It allows giving the possible short and long options
       in a simple list and provides --help and --version output to the user of the program.

       Usage: create an array of shevek::args::option, containing the desired options. create an
       instance of args and pass it argc and argv on the constructor. It will call all the
       callbacks of the options from the constructor. size () and operator[] can be used to
       access the non-option arguments.

       PACKAGE_BUGREPORT, char const * programname = PACKAGE_NAME, char const * packagename =
       PACKAGE_TARNAME, char const * version = PACKAGE_VERSION)
       Parse the commandline. Only the default arguments (--help, -h and --version) are
       understood.
