26 *       data from Yohoho! Puzzle Pirates via the Java Accessibility
27 *       API.
28 *
29 *       MarketUploader initializes after the main YPP window has
30 *       initialized. It provides a simple window with a "Capture
31 *       Market Data" button displayed.  Upon clicking this button, a
32 *       progress dialog is displayed, and the data is processed and
33 *       submitted to the YARRG and PCTB servers. If any errors occur,
34 *       an error dialog is shown, and processing returns, the button
35 *       becoming re-enabled.
