Installing an empty directory with RPM

In my install section of my rpm Spec file I h开发者_StackOverflowave a bunch of mkdir's to create the directories I need. The ones that don't have any files installed in them get pruned out in the end and don't end up getting created. How can I ensure that the empty directories get created when it is all said and done?

In your %files section:

%files
%dir /my/directory/name
