   4
   5   Simple stub function for UnZip DLL (or shared library, whatever); does
   6   exactly the same thing as normal UnZip, except for additional printf()s
   7   of various version numbers, solely as a demonstration of what can/should
   8   be checked when using the DLL.  (If major version numbers ever differ,
   9   assume program is incompatible with DLL--especially if DLL version is
  10   older.  This is not likely to be a problem with *this* simple program,
  11   but most user programs will be much more complex.)
