/**
* This adapter sends log output to SLF4J. SLF4J supports multiple
* implementations such as Logback, Log4j, Jakarta Commons Logging (JCL), JDK
* 1.4 logging, x4juli, and Simple Log. To use SLF4J, you need to add the
* required jar files to the classpath, and set the trace level to 4 when
* opening a database:
*
*
* jdbc:h2:˜/test;TRACE_LEVEL_FILE=4
*
*
* The logger name is 'h2database'.
