+/**
+ * This tool is used to help create the class list for class data sharing.
+ *
+ * The classlist is produced internally by first running a select number of
+ * startup benchmarks with the -XX:DumpLoadedClassList=<file> option, then
+ * running this tool in the following fashion to produce a complete classlist:
+ *
+ * jjs -scripting makeClasslist.js -- list1 list2 list3 > classlist.platform
+ *
+ * The lists should be listed in roughly smallest to largest order based on
+ * application size.
+ *
+ * After generating the classlist it's necessary to add a checksum (using
+ * AddJsum.java) before checking it into the workspace as the corresponding
+ * platform-specific classlist, such as make/data/classlist/classlist.linux
