+// TXMsgBox.h
+//
+// A TXMsgBox is a specialised pop-up dialog window, designed to present
+// the user with a small amount of textual information, and potentially to
+// obtain their response.
+// TXMsgBoxes are always modal, and may have an Ok button, Ok+Cancel buttons,
+// or Yes+No buttons.
+// The MsgBox helper function creates a TXMsgBox on the fly, runs it, and
+// returns the result.
