Error message "Manifest file missing in module"

When importing an OpenCms module sometimes you get the error message

Error uploading the module [MODULENAME].zip.
Manifest file missing in module [PATH_TO_MODULE][MODULENAME].zip.

In most of the cases the problem is, that the zip file you try to import is not the module.zip, but another zip file which includes the real module.zip
