+/*  URLView 2.11
+	written by William Kakes of Tall Hill Software.
+	
+	This class provides an underlined and clickable BStringView
+	that will launch the web browser, e-mail program, or FTP client
+	when clicked on.  Other features include hover-highlighting,
+	right-click	menus, and drag-and-drop support.
+
+	You are free to use URLView in your own programs (both open-source
+	and closed-source) free of charge, but a mention in your read me
+	file or your program's about box would be appreciated.  See
+	http://www.tallhill.com	for current contact information.
+	
+	URLView is provided as-is, with no warranties of any kind.  If
+	you use it, you are on your own.
