| /** |
| * Entry point for the layoutlib_create tool. |
| * <p/> |
| * The tool does not currently rely on any external configuration file. |
| * Instead the configuration is mostly done via the {@link CreateInfo} class. |
| * <p/> |
| * For a complete description of the tool and its implementation, please refer to |
| * the "README.txt" file at the root of this project. |
| * <p/> |
| * For a quick test, invoke this as follows: |
| * <pre> |
| * $ make layoutlib |
| * </pre> |
| * which does: |
| * <pre> |
| * $ make layoutlib_create <bunch of framework jars> |
| * $ java -jar out/host/linux-x86/framework/layoutlib_create.jar \ |
| * out/host/common/obj/JAVA_LIBRARIES/temp_layoutlib_intermediates/javalib.jar \ |
| * out/target/common/obj/JAVA_LIBRARIES/core_intermediates/classes.jar \ |
| * out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar |
