+/**
+ * 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:
+ * elemtary_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 example_group 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`
