 /**
- *
+ * A Video recording AppState that records the screen output into an AVI file with
+ * M-JPEG content. The file should be playable on any OS in any video player.<br/>
+ * The video recording starts when the state is attached and stops when it is detached
+ * or the application is quit. You can set the fileName of the file to be written when the
+ * state is detached, else the old file will be overwritten.
