/**
* 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
