To pass additional arguments to the Java Virtual Machine (JVM), you can use the -JVM script flag. For example, assume you want to override the default maximum heap size setting of 1024 MB that is hardcoded in the scripts with a setting of 2048 MB. The command line might be as follows:

.\bin\web-crawler -d 2 -s conf\web\intsites\int.lst -JVM -Xmx2g

Keep in mind that this flag must be the last flag on the command line, because any arguments that follow it are appended to those passed to the JVM.
