I didn't really see it spelled out in the ones a looked at. I mean I saw that there is a difference between a shell and a theme, but I didn't see where it actually said that they weren't traditionally packaged together... in LS.

Add to that I didn't find any of the documentation that many of the tutorials said was packaged with the installed files...
