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