  11   unzipstb.c
  12
  13   Simple stub function for UnZip DLL (or shared library, whatever); does
  14   exactly the same thing as normal UnZip, except for additional printf()s
  15   of various version numbers, solely as a demonstration of what can/should
  16   be checked when using the DLL.  (If major version numbers ever differ,
  17   assume program is incompatible with DLL--especially if DLL version is
  18   older.  This is not likely to be a problem with *this* simple program,
  19   but most user programs will be much more complex.)
