+ * See Changelog.txt for version history
+ *
+ * Development Notes:
+ * * This version of SWFUpload requires Flash Player 9.0.28 and should autodetect the correct flash version.
+ * * In Linux Flash Player 9 setting the post file variable name does not work. It is always set to "Filedata".
+ * * There is a lot of repeated code that could be refactored to single functions. Feel free.
+ * * It's dangerous to do "circular calls" between Flash and JavaScript. I've taken steps to try to work around issues
+ * by having the event calls pipe through setTimeout. However you should still avoid calling in to Flash from
+ * within the event handler methods. Especially the "startUpload" event since it cannot use the setTimeout hack.
