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.)
