/**
* @file Ecore_Getopt.h
* @brief Contains powerful getopt replacement.
*
* This replacement handles both short (-X) or long options (--ABC)
* options, with various actions supported, like storing one value and
* already converting to required type, counting number of
* occurrences, setting true or false values, show help, license,
* copyright and even support user-defined callbacks.
*
* It is provided a set of C Pre Processor macros so definition is
* straightforward.
*
* Values will be stored elsewhere indicated by an array of pointers
* to values, it is given in separate to parser description so you can
* use multiple values with the same parser.
