3 * rolex.c: Windows clock application for WINE (by Jim Peterson) *
5 * This is a translation of a Turbo Pascal OWL application I made *
6 * once, so it's a little flaky (tons of globals, functions that *
7 * could have been in-lined, etc.). The source code should easily *
8 * compile with a standard Win32 C compiler. *
10 * To try it out, type 'make rolex'. *
