## Package org.slf4j.instrumentation Description

Java instrumentation routines for SLF4J.

Byte code instrumentation is an way to change behaviour of java classes at load time. This is done in-between the original byte codes are retrieved and the class object is constructed by the class loader. Currently this depends on the javassist library from JBoss (which in turn uses it extensively in their application server).
