IMPORTANT NOTE:
The sample Windows executables for HTTP fakefile mode included
with INetSim change with each version due to them being rebuilt.
If your setup relies on INetSim to continue serving the historical
binaries included with previous versions, see
/usr/share/inetsim/contrib/sample.README for additional information.
