 * Simple Edje example illustrating the edje_codegen usage.
4
 *
5
 * edje_codegen is a tool that generates code to acessing the parts and programs
6
 * with the keyword "api" of a specified group. This tool make easier working
7
 * with edje avoiding common errors caused by typos when acessing the parts
8
 * and/or programs.
9
 *
10
 * To use the edje_codegen:
11
 * edje_codegen --prefix <myapp_myobj> <input.edj> <a_group> <source.c> <header.h>
12
 *
13
 * In case of this example:
14
 * edje_codegen --prefix=codegen_example codegen.edj group_example \
15
	codegen_example_generated.c codegen_example_generated.h
16
 *
17
 * @verbatim
18
 * edje_cc codegen.edc && edje_codegen --prefix=codegen_example codegen.edj \
19
 * example_group codegen_example_generated.c codegen_example_generated.h
20
 * gcc -c codegen_example_generated.c `pkg-config --libs --cflags ecore-evas edje`
21
 * gcc -o edje-codegen-example codegen_example_generated.o \
22
 * edje-codegen-example.c `pkg-config --libs --cflags ecore-evas edje`
23
 * @endverbatim
