Adding a directory to the install

I've looked through all the information that I can find, but I can't seem to see any way to make NSIS include a directory in the installation. The reason that just listing all the files doesn't work, is that the contents of the directory is somewhat dynamic--files can be added and removed daily.
Am I missing something in the docs somewhere? or is this a capability that should be added?

Thanks

Use the /r switch with the File command.

See, I knew there had to be a way to do it, and I just missed that flag. Thanks!!!!
