+ * 
+ * This application updates the Monster Book drop data with the actual underlying drop data from
+ * the Maplestory database specified by the URL below.
+ * 
+ * The original file "MonsterBook.img.xml" from String.wz must be copied to the directory of this application and only then
+ * executed. This program will generate another file that must replace the original server file to make the effects take place
+ * to on your server.
+ * 
+ * After replacing on server, this XML must be updated on the client via WZ Editor (HaRepack for instance). Once inside the repack,
+ * remove the property 'MonsterBook.img' inside 'string.wz' and choose to import the xml generated with this software.
