+// Name:        wxpoem.h
+// Purpose:     A small C++ program which displays a random poem on
+//              execution. It also allows search for poems containing a
+//              string.
+//              It requires winpoem.dat and creates winpoem.idx.
+//              Original version (WinPoem) written in 1994.
+//              This has not been rewritten in a long time so
+//              beware, inelegant code!
