/**
* Simple Elementary example illustrating how to use elementary_codegen.
*
* elementary_codegen is a tool that generates code to acessing the
* parts and programs with the keyword "api" of a specified
* group. This tool make easier working with edje avoiding common
* misspelling errors when acessing the parts and/or programs.
*
* To use the elementary_codegen:
* elementary_codegen --prefix <myapp_myobj> <input.edj> <a_group> <source.c> <header.h>
*
* In the case of this example:
* elementary_codegen --prefix=codegen_example codegen_example.edj \
* elm/example/mylayout/default codegen_example_generated.c codegen_example_generated.h
*
* @verbatim
* edje_cc codegen_example.edc && elementary_codegen --prefix=codegen_example \
* codegen_example.edj elm/example/mylayout/default codegen_example_generated.c \
* codegen_example_generated.h
* gcc -c codegen_example_generated.c `pkg-config --libs --cflags ecore-evas edje elementary`
* gcc -o codegen_example codegen_example_generated.o \
* codegen_example.c `pkg-config --libs --cflags ecore-evas edje elementary`
* @endverbatim
