Is there a feature you are looking for that you want to enable in
particular? I can see in the code from the above referenced JAR that the
YUI compressor is called with this method:compress(Writer out, int
linebreak, boolean munge, boolean verbose, boolean
preserveAllSemiColons, boolean disableOptimizations)with these
parameterscompressor.compress(out, 0, true, false, false, false);
