// 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!
