This package contains classes to represent the various elements of class files.
A class file is represented by the {@link proguard.classfile.Clazz
Clazz} interface. This interface currently has two alternative
representations:
- {@link proguard.classfile.ProgramClass}:
    a complete representation that can be read, modified, and written back.
- {@link proguard.classfile.LibraryClass}:
    an incomplete representation that can be only be read. It is however
    more compact than- ProgramClass, and sufficient for
    analyzing class files from library jars.
