<P>
Simple wrapper for the servlet log. This passes Velocity log
messages to ServletContext.log(String). You may configure the
level of output in your velocity.properties by adding the
"runtime.log.logsystem.servlet.level" property with one of the
following values: error, warn, info, debug, or trace. The default
is trace.
