Django micro-frameworks

Recently I was searching for Django micro-frameworks (or frameworks
built on top of/out of Django, if you will). I knew there were some, I
just couldn’t find any. Thanks to a bit of luck and my excellent
Google-fu, I found four. These are, to my knowledge, all Django
micro-frameworks available:

I haven’t had time to play with any of them since. If you have any
experience with one of there micro-frameworks, please let me know in
the comments.
