-Provides an implementation for optional class, field and method attributes.
-
-<p>
-
-By default ASM strips optional attributes, in order to keep them in
-the bytecode that is being readed you should pass an array of required attribute
-instances to {@link org.objectweb.asm.ClassReader#accept(org.objectweb.asm.ClassVisitor, org.objectweb.asm.Attribute[], boolean) ClassReader.accept()} method.
-In order to add custom attributes to the manually constructed bytecode concrete
-subclasses of the {@link org.objectweb.asm.Attribute Attribute} can be passed to
-the visitAttribute methods of the
-{@link org.objectweb.asm.ClassVisitor ClassVisitor},
-{@link org.objectweb.asm.FieldVisitor FieldVisitor} and
-{@link org.objectweb.asm.MethodVisitor MethodVisitor} interfaces.

-<body>
-Provides a small and fast bytecode manipulation framework.
-
-<p>
-The <a href="http://www.objectweb.org/asm">ASM</a> framework is organized
-around the {@link org.objectweb.asm.ClassVisitor ClassVisitor},
-{@link org.objectweb.asm.FieldVisitor FieldVisitor} and
-{@link org.objectweb.asm.MethodVisitor MethodVisitor} interfaces, which allow
-one to visit the fields and methods of a class, including the bytecode
-instructions of each method.
-
-<p>
-In addition to these main interfaces, ASM provides a {@link
-org.objectweb.asm.ClassReader ClassReader} class, that can parse an
-existing class and make a given visitor visit it. ASM also provides
-a {@link org.objectweb.asm.ClassWriter ClassWriter} class, which is
-a visitor that generates Java class files.
-
-<p>
-In order to generate a class from scratch, only the {@link
-org.objectweb.asm.ClassWriter ClassWriter} class is necessary. Indeed,
-in order to generate a class, one must just call its visit<i>XXX</i>
-methods with the appropriate arguments to generate the desired fields
-and methods. See the "helloworld" example in the ASM distribution for
-more details about class generation.
-
-<p>
-In order to modify existing classes, one must use a {@link
-org.objectweb.asm.ClassReader ClassReader} class to analyze
-the original class, a class modifier, and a {@link org.objectweb.asm.ClassWriter
-ClassWriter} to construct the modified class. The class modifier
-is just a {@link org.objectweb.asm.ClassVisitor ClassVisitor}
-that delegates most of the work to another {@link org.objectweb.asm.ClassVisitor
-ClassVisitor}, but that sometimes changes some parameter values,
-or call additional methods, in order to implement the desired
-modification process. In order to make it easier to implement such
-class modifiers, ASM provides the {@link org.objectweb.asm.ClassAdapter
-ClassAdapter} and {@link org.objectweb.asm.MethodAdapter MethodAdapter}
-classes, which implement the {@link org.objectweb.asm.ClassVisitor ClassVisitor}
-and {@link org.objectweb.asm.MethodVisitor MethodVisitor} interfaces by
-delegating all work to other visitors. See the "adapt" example in the ASM
-distribution for more details about class modification.
-
-<p>
-The size of the core ASM library, <tt>asm.jar</tt>, is only 31KB, which is much
-more smaller than
-the size of the <a href="http://jakarta.apache.org/bcel">BCEL</a> library (350KB
-without the class verifier), and than the size of the
-<a href="http://serp.sourceforge.net">SERP</a> library (150KB). ASM is also
-much more faster than these tools. Indeed the overhead of a load time class
-transformation process is of the order of 60% with ASM, 700% or more with BCEL,
-and 1100% or more with SERP (see the <tt>test/perf</tt> directory in the ASM
-distribution)!
