// WikiBhasha launch helper script.
// Description: this script eases the procedure to launch WikiBhasha by instrumenting
// wikipedia pages with links and options to launch the application. It executes the
// same routine as the bookmarklet and is portable across Wikipedia installations.
//
// The current options to launch WikiBhasha are:
// 1. Looks for "action=edit" in the URL and check if toolbar exists. if present adds a
//    icon to the toolbar for launching WikiBhasha.
// 2. inserts a "WikiBhasha" option in the left side toolbox menu.
// 3. Looks for "wbAutoLaunch=true" in the URL and launch WikiBhasha.

	// the application
