Sekizai means "blocks" in Japanese, and that's what this app provides. A fresh
look at blocks. With django-sekizai you can define placeholders where your
blocks get rendered and at different places in your templates append to those
blocks. This is especially useful for css and javascript. Your subtemplates can
now define css and javscript files to be included, and the css will be nicely
put at the top and the javascript to the bottom, just like you should. Also
sekizai will ignore any duplicate content in a single block.
