// 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!
