Description
Keyword; lets you access classes without specifying their fully qualified names. For example, if you
want to use a custom class macr.util.users.UserClass in a script, you must refer to it by its fully

// before importing
var myUser:macr.util.users.UserClass = new macr.util.users.UserClass();
// after importing
import macr.util.users.UserClass;
var myUser:UserClass = new UserClass();

fully qualified names (
to the other frame that imports the classes in that package.
