A JRuby adaption and gem packaging of the {Simple Logging Facade for Java}[]. Provides all jar dependencies and a Ruby Logger compatible facade. SLF4J is a java logging abstraction and set of adapters to various concrete logging implementations and legacy logging APIs. The slf4j gem adds a ruby core Logger compatible facade to SLF4J, and makes any needed adapters available to JRuby applications. This makes it possible to unify and control logging output of both java and ruby components in a JRuby application.
