+ drawtext.c -- Test the DrawText functions - Based on
+ HELLOWIN.C -- Displays "Hello, Windows 95!" in client area
+ (c) Charles Petzold, 1996
+
+drawtext is a program that exercises the capabilities of the DrawText and
+DrawTextEx functions in order to provide information for and testing of the
+Wine product.
+
+Calling:
+drawtext ?
+or
+drawtext [<page setting>[<Tab setting>[<Left Margin>[<Right Margin>]]] "Text"
+
+To be done:
+1. Add the flags e.g. reset_text to the arguments
+2. Improve the text modification reporting especially to see what happens
+ after the \0 inserted during word ellipsification.
