Flowerbed is a web application that allows one to grow a flower from a
preselected group of WSGI apps. Flowerbed presents a nested ordered
list of web applications. You drag one of the preselected webapps to a
place on the list. This will add the webapp to configuration and the
website and give a default path descriminator (e.g. /blog for
bitsyblog). You should be able to download the configuration in either
JSON or ini format. In addition, you can download a complete flower
python package created from a template that will allow the whole site
to be installed and managed locally.
