+ * @class JSDOC.Packer
+ * Create a new packer
+ *
+ * Usage:
+ * <code>
+ *
+var x = new JSDOC.Packer(
+ [ "/location/of/file1.js", "/location/of/file2.js", ... ],
+ "/location/of"
+);
+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 horrifically slow.
+ * Best to use lot's of small classes, and use it to merge, as it will cache the compaction
+ *
+ *
+ *
+ * @param {Array} files List of Files - MUST BE WITH ABSOLUTE PATH eg. [ '/usr/src/xyz/abc.js', .... ]
+ * @param {String} source_path top level directory of source (used to work out the relative names for the minimized temp files)
