+ * <code>
+ *
+Packer = imports['JSDOC/Packer.js'].Packer;
+var x = new Packer({
+
+ files : [ "/location/of/file1.js", "/location/of/file2.js", ... ],
+ target : "/tmp/output.js",
+ debugTarget : "/tmp/output.debug.js", // merged file without compression.
+ debugTranslateTarget : "/tmp/output.translate.js", // merged with translation
+ // and no compression
+ translateJSON: "/tmp/translate.json",
+
+
+);
+x.packFiles(
+ "/location/of/temp_batch_dir",
+ "/location/of/output-compacted-file.js",
+ "/location/of/output-debug-merged-file.js"
+);
+
+ *</code>
+ *
+ * Notes for improving compacting:
+ * if you add a jsdoc comment
+ * <code>
+ * /**
+ * eval:var:avarname
+ * eval:var:bvarname
+ * ....
+ * </code>
+ * directly before an eval statement, it will compress all the code around the eval,
+ * and not rename the variables 'avarname'
+ *
+ * Dont try running this on a merged uncompressed large file - it's used to be horrifically slow. not sure about now..
+ * Best to use lot's of small classes, and use it to merge, as it will cache the compaction
+ *
+ *
+ *
+ * Notes for translation
+ * - translation relies on you using double quotes for strings if they need translating
+ * - single quoted strings are ignored.
+ *
+ * Generation of indexFiles
+ * - translateIndex = the indexfile
+ *
+ *
+ *
