#include "zpp.h"

/////////////////////////////////////////////////////////////////////////
//
// test harness 
//
// this program assumes that a zip file called "zpp.zip" exists in
// the directory that you are running it in.  it assumes that a file
// "readme.htm" exists in that .ZIP file.  it also assumes that there's
// a file called "notinzip.txt" in the current directory which is NOT
// in the ZIP file (to test filesystem fallback)
//
// this program does not illustrate opening of all zip files, attributes,
// etc.  it's pretty basic.
